-## Changes in this resubmission
-
-> Package names are case sensitive. (in title:) --> 'xaringan' 
-
-The title was changed accordingly.
-
-> Please do not modify the global environment (e.g. by using <<- or  
-> assign() without a specified environment) in your functions. 
-
-`assign()` is used but always with an explicit environment to ensure
-that the global environment is not modified.
-
-> Please make sure you do not write or download anything without the 
-> user's permission.
-
-I've verified that all file outputs are consented, either by setting a function
-argument to the path of an outfile or by prompt. In one case where a required
-file needs to be downloaded, the user's consent is requested prior to the
-download. If the user consents, the file is downloaded into the temp folder.
-
-> Please make sure that you do not change the user's options, par or 
-> working directory.
-
-The global options are not modified by any functions in the package. There are
-a few places in the tests where options are temporarily modified for the test,
-but the options are reverted when exiting the scope of the test.
+0 errors | 0 warnings | 0 notes
 
-> Missing Rd-tags: \value, \arguments
+No reverse dependencies.
 
-I've added the missing Rd tags in all files.
+Replaces previous submission with corrected links 
+for three URLs that were moved to a new location.

+## Typography
 
-You are recommended to use the [RStudio IDE](https://www.rstudio.com/products/rstudio/), but you do not have to.
+Text can be **bold**, _italic_, ~~strikethrough~~, or `inline code`.

+## Colors
 
-# Hello Ninja
+- <span style="color: var(--text-color)">Text Color</span>
 
-As a presentation ninja, you certainly should not be satisfied by the "Hello World" example. You need to understand more about two things:
+- <span style="color: var(--header-color); font-family: var(--header-font-family);">Header Color</span>
 
-1. The [remark.js](https://remarkjs.com) library;
+- <span style="color: var(--link-color)">Link Color</span>
 
-1. The **xaringan** package;
+- <span style="color: var(--text-bold-color); font-weight: bold;">Bold Color</span>
 
-Basically **xaringan** injected the chakra of R Markdown (minus Pandoc) into **remark.js**. The slides are rendered by remark.js in the web browser, and the Markdown source needed by remark.js is generated from R Markdown (**knitr**).

-# remark.js
+# Big Topic or Inverse Slides `#`
 
-You can see an introduction of remark.js from [its homepage](https://remarkjs.com). You should read the [remark.js Wiki](https://github.com/gnab/remark/wiki) at least once to know how to
+## Slide Headings `##`
 
-- create a new slide (Markdown syntax<sup>*</sup> and slide properties);
+### Sub-slide Headings `###`
 
-- format a slide (e.g. text alignment);
+#### Bold Call-Out `####`
 
-- configure the slideshow;
+This is a normal paragraph text. Only use header levels 1-4.
 
-- and use the presentation (keyboard shortcuts).
+##### Possible, but not recommended `#####`
 
-It is important to be familiar with remark.js before you can understand the options in **xaringan**.
-
-.footnote[[*] It is different with Pandoc's Markdown! It is limited but should be enough for presentation purposes. Come on... You do not need a slide for the Table of Contents! Well, the Markdown support in remark.js [may be improved](https://github.com/gnab/remark/issues/142) in the future.]
+###### Definitely don't use h6 `######`

-# remark.js vs xaringan
-
-Some differences between using remark.js (left) and using **xaringan** (right):
-
-.pull-left[
-1. Start with a boilerplate HTML file;
-
-1. Plain Markdown;
-
-1. Write JavaScript to autoplay slides;
-
-1. Manually configure MathJax;
-
-1. Highlight code with `*`;
-
-1. Edit Markdown source and refresh browser to see updated slides;
-]
-
-.pull-right[
-1. Start with an R Markdown document;
-
-1. R Markdown (can embed R/other code chunks);
-
-1. Provide an option `autoplay`;
-
-1. MathJax just works;<sup>*</sup>
-
-1. Highlight code with `{{}}`;
-
-1. The RStudio addin "Infinite Moon Reader" automatically refreshes slides on changes;

+## Blocks
 
 ---
 
-# Math Expressions
-
-You can write LaTeX math expressions inside a pair of dollar signs, e.g. &#36;\alpha+\beta$ renders $\alpha+\beta$. You can use the display style with double dollar signs:
-
-```
-$$\bar{X}=\frac{1}{n}\sum_{i=1}^nX_i$$
-```
+### Blockquote
 
-$$\bar{X}=\frac{1}{n}\sum_{i=1}^nX_i$$
-
-Limitations:
-
-1. The source code of a LaTeX math expression must be in one line, unless it is inside a pair of double dollar signs, in which case the starting `$$` must appear in the very beginning of a line, followed immediately by a non-space character, and the ending `$$` must be at the end of a line, led by a non-space character;
-
-1. There should not be spaces after the opening `$` or before the closing `$`.
-
-1. Math does not work on the title slide (see [#61](https://github.com/yihui/xaringan/issues/61) for a workaround).
+> This is a blockquote following a header.
+>
+> When something is important enough, you do it even if the odds are not in your favor.

-
-# Tables
-
-If you want to generate a table, make sure it is in the HTML format (instead of Markdown or other formats), e.g.,
+#### JavaScript
 
-```{r}
-knitr::kable(head(mtcars), format = 'html')
+```js
+var fun = function lang(l) {
+  dateformat.i18n = require('./lang/' + l)
+  return true;
+}
 ```
 
 ---
 
-# HTML Widgets
-
-I have not thoroughly tested HTML widgets against **xaringan**. Some may work well, and some may not. It is a little tricky.
-
-Similarly, the Shiny mode (`runtime: shiny`) does not work. I might get these issues fixed in the future, but these are not of high priority to me. I never turn my presentation into a Shiny app. When I need to demonstrate more complicated examples, I just launch them separately. It is convenient to share slides with other people when they are plain HTML/JS applications.
+### More R Code
 
-See the next page for two HTML widgets.

-# Some Tips
-
-- When you use the "Infinite Moon Reader" addin in RStudio, your R session will be blocked by default. You can click the red button on the right of the console to stop serving the slides, or use the _daemonized_ mode so that it does not block your R session. To do the latter, you can set the option
-
-    ```r
-    options(servr.daemon = TRUE)
-    ```
-    
-    in your current R session, or in `~/.Rprofile` so that it is applied to all future R sessions. I do the latter by myself.
-    
-    To know more about the web server, see the [**servr**](https://github.com/yihui/servr) package.
-
 --
 
-- Do not forget to try the `yolo` option of `xaringan::moon_reader`.
-
-    ```yaml
-    output:
-      xaringan::moon_reader:
-        yolo: true
-    ```
-
----
-
-# Some Tips
+```{r message=TRUE}
+message("Just a friendly message")
+```
 
-- Slides can be automatically played if you set the `autoplay` option under `nature`, e.g. go to the next slide every 30 seconds in a lightning talk:
+--
 
-    ```yaml
-    output:
-      xaringan::moon_reader:
-        nature:
-          autoplay: 30000
-    ```
+```{r warning=TRUE}
+warning("This could be bad...")
+```
 
 --
 
-- A countdown timer can be added to every page of the slides using the `countdown` option under `nature`, e.g. if you want to spend one minute on every page when you give the talk, you can set:
-
-    ```yaml
-    output:
-      xaringan::moon_reader:
-        nature:
-          countdown: 60000
-    ```
+```{r error=TRUE}
+stop("I hope you're sitting down for this")
+```
 
-    Then you will see a timer counting down from `01:00`, to `00:59`, `00:58`, ... When the time is out, the timer will continue but the time turns red.

-# Some Tips
-
-- There are several ways to build incremental slides. See [this presentation](https://slides.yihui.name/xaringan/incremental.html) for examples.
-
-- The option `highlightLines: true` of `nature` will highlight code lines that start with `*`, or are wrapped in `{{ }}`, or have trailing comments `#<<`;
-
-    ```yaml
-    output:
-      xaringan::moon_reader:
-        nature:
-          highlightLines: true
-    ```
-
-    See examples on the next page.
+## Tables

-# Some Tips
-
-
-.pull-left[
-An example using a leading `*`:
-
-    ```r
-    if (TRUE) {
-    ** message("Very important!")
-    }
-    ```
-Output:
-```r
-if (TRUE) {
-* message("Very important!")
-}
-```
-
-This is invalid R code, so it is a plain fenced code block that is not executed.
-]
-
-.pull-right[
-An example using `{{}}`:
-
-    `r ''````{r tidy=FALSE}
-    if (TRUE) {
-    *{{ message("Very important!") }}
-    }
-    ```
-Output:
-```{r tidy=FALSE}
-if (TRUE) {
-{{ message("Very important!") }}
-}
+```{r}
+tibble::as_tibble(mtcars)
 ```
 
-It is valid R code so you can run it. Note that `{{}}` can wrap an R expression of multiple lines.
-]
-
 ---
 
-# Some Tips
-
-An example of using the trailing comment `#<<` to highlight lines:
-
-````markdown
-`r ''````{r tidy=FALSE}
-library(ggplot2)
-ggplot(mtcars) + 
-  aes(mpg, disp) + 
-  geom_point() +   #<<
-  geom_smooth()    #<<
+```{r}
+knitr::kable(head(mtcars), format = 'html')
 ```
-````
 
-Output:
+---
 
-```{r tidy=FALSE, eval=FALSE}
-library(ggplot2)
-ggplot(mtcars) + 
-  aes(mpg, disp) + 
-  geom_point() +   #<<
-  geom_smooth()    #<<
+```{r}
+DT::datatable(head(mtcars), fillContainer = FALSE, options = list(pageLength = 4))
 ```
 
 ---
+layout: true
 
-# Some Tips
-
-- To make slides work offline, you need to download a copy of remark.js in advance, because **xaringan** uses the online version by default (see the help page `?xaringan::moon_reader`).
-
-- You can use `xaringan::summon_remark()` to download the latest or a specified version of remark.js. By default, it is downloaded to `libs/remark-latest.min.js`.
-
-- Then change the `chakra` option in YAML to point to this file, e.g.
-
-    ```yaml
-    output:
-      xaringan::moon_reader:
-        chakra: libs/remark-latest.min.js
-    ```
-
-- If you used Google fonts in slides (the default theme uses _Yanone Kaffeesatz_, _Droid Serif_, and _Source Code Pro_), they won't work offline unless you download or install them locally. The Heroku app [google-webfonts-helper](https://google-webfonts-helper.herokuapp.com/fonts) can help you download fonts and generate the necessary CSS.
+## Lists
 
 ---
 
-# Macros
-
-- remark.js [allows users to define custom macros](https://github.com/yihui/xaringan/issues/80) (JS functions) that can be applied to Markdown text using the syntax `![:macroName arg1, arg2, ...]` or `![:macroName arg1, arg2, ...](this)`. For example, before remark.js initializes the slides, you can define a macro named `scale`:
+.pull-left[
+#### Here is an unordered list:
 
-    ```js
-    remark.macros.scale = function (percentage) {
-      var url = this;
-      return '<img src="' + url + '" style="width: ' + percentage + '" />';
-    };
-    ```
+*   Item foo
+*   Item bar
+*   Item baz
+*   Item zip
+]
 
-    Then the Markdown text
+.pull-right[
 
-    ```markdown
-    ![:scale 50%](image.jpg)
-    ```
+#### And an ordered list:
 
-    will be translated to
-    
-    ```html
-    <img src="image.jpg" style="width: 50%" />
-    ```
+1.  Item one
+1.  Item two
+1.  Item three
+1.  Item four
+]
 
 ---
 
-# Macros (continued)
+### And a nested list:
 
-- To insert macros in **xaringan** slides, you can use the option `beforeInit` under the option `nature`, e.g.,
-
-    ```yaml
-    output:
-      xaringan::moon_reader:
-        nature:
-          beforeInit: "macros.js"
-    ```
-
-    You save your remark.js macros in the file `macros.js`.
-
-- The `beforeInit` option can be used to insert arbitrary JS code before `remark.create()`. Inserting macros is just one of its possible applications.

-# CSS
+### Nesting an ol in ul in an ol
 
-Among all options in `xaringan::moon_reader`, the most challenging but perhaps also the most rewarding one is `css`, because it allows you to customize the appearance of your slides using any CSS rules or hacks you know.
-
-You can see the default CSS file [here](https://github.com/yihui/xaringan/blob/master/inst/rmarkdown/templates/xaringan/resources/default.css). You can completely replace it with your own CSS files, or define new rules to override the default. See the help page `?xaringan::moon_reader` for more information.

-# CSS
-
-For example, suppose you want to change the font for code from the default "Source Code Pro" to "Ubuntu Mono". You can create a CSS file named, say, `ubuntu-mono.css`:
-
-```css
-@import url(https://fonts.googleapis.com/css?family=Ubuntu+Mono:400,700,400italic);
-
-.remark-code, .remark-inline-code { font-family: 'Ubuntu Mono'; }
-```
-
-Then set the `css` option in the YAML metadata:
-
-```yaml
-output:
-  xaringan::moon_reader:
-    css: ["default", "ubuntu-mono.css"]
-```
-
-Here I assume `ubuntu-mono.css` is under the same directory as your Rmd.
-
-See [yihui/xaringan#83](https://github.com/yihui/xaringan/issues/83) for an example of using the [Fira Code](https://github.com/tonsky/FiraCode) font, which supports ligatures in program code.

-# Themes
-
-Don't want to learn CSS? Okay, you can use some user-contributed themes. A theme typically consists of two CSS files `foo.css` and `foo-fonts.css`, where `foo` is the theme name. Below are some existing themes:
-
-```{r}
-names(xaringan:::list_css())
-```
-
-To use a theme, you can specify the `css` option as an array of CSS filenames (without the `.css` extensions), e.g.,
-
-```yaml
-output:
-  xaringan::moon_reader:
-    css: [default, metropolis, metropolis-fonts]
+```{r plot-example}
+library(ggplot2)
+(g <- ggplot(mpg) + aes(hwy, cty, color = class) + geom_point())
 ```
 
-If you want to contribute a theme to **xaringan**, please read [this blog post](https://yihui.name/en/2017/10/xaringan-themes).

-The R package name **xaringan** was derived<sup>1</sup> from **Sharingan**, a dōjutsu in the Japanese anime _Naruto_ with two abilities:

-I think a presentation is basically a way to communicate insights to the audience, and a great presentation may even "hypnotize" the audience.<sup>2,3</sup>

-[1] In Chinese, the pronounciation of _X_ is _Sh_ /ʃ/ (as in _shrimp_). Now you should have a better idea of how to pronounce my last name _Xie_.
