\item{plot.background.color}{Color of plot background, passed to \code{plot.background}}

\item{panel.border.color}{Color of plot panel border}

\item{with.panel.grid}{If \code{FALSE} gridlines in plot are removed}

\item{panel.grid.color, panel.grid.linetype}{Color and linetype of panel grid, passed to \code{panel.grid}}

\item{axis.text.color, axis.text.size}{Color and size of axis text}

\item{base_theme}{Starting theme of plot, default is

\section{Functions}{
\itemize{
\item \code{theme_pomological_nobg}: Pomological theme with white (transparent) background

\item \code{theme_pomological_plain}: A "plain" pomological theme with white
background and normal fonts.
}}

\section{Fonts}{

Complete the pomological watercolor theme with a handwriting or cursive font.
The following fonts from \href{https://fonts.google.com}{Google Fonts} work well.
Visit the links below to install on your system.
\itemize{
\item \href{https://fonts.google.com/specimen/Homemade+Apple/}{Homemade Apple}
\item \href{https://fonts.google.com/specimen/Amatic+SC/}{Amatic SC}
\item \href{https://fonts.google.com/specimen/Mr+Bedfort/}{Mr. Bedfort}
}

Fonts with R are notoriously tricky, so these may not work well for you. If
you have installed the fonts but they aren't showing up or working, you can
always try running \code{extrafont::font_import()} or \code{extrafont::load_fonts()} in
the session or RMarkdown document. Or you can use \code{\link[=theme_pomological_plain]{theme_pomological_plain()}}.
