\arguments{
\item{x, y}{Vector of values or List of vectors of values. y is optional.}

\item{width}{The width of the plot in pixel}

\item{height}{The height of the plot in pixel}

\item{res}{The resolution of the plot. Default is 300.}

\item{same_lim}{T/F. If x is a list of vectors, should all the plots be
plotted in the same range? Default is True.}

\item{xlim, ylim}{Manually specify plotting range in the form of
\code{c(0, 10)}.}

\item{xaxt}{On/Off for xaxis text}

\item{yaxt}{On/Off for yaxis text}

\item{ann}{On/Off for annotations (titles and axis titles)}

\item{col}{Color for the fill of the histogram bar/boxplot box.}

\item{border}{Color for the border.}

\item{frame.plot}{On/Off for surrounding box (\code{spec_line} only). Default
is False.}

\item{lwd}{Line width for \code{spec_line}; within \code{spec_line}, the \code{minmax}
argument defaults to use this value for \code{cex} for points. Default is 2.}

\item{pch, cex}{Shape and size for points (if type is other than "l").}

\item{type}{Passed to \code{plot}, often one of "l", "p", or "b", see
\code{\link[graphics:plot.default]{graphics::plot.default()}} for more details. Ignored when 'polymin' is
not 'NA'.}

\item{polymin}{Special argument that converts a "line" to a polygon,
where the flat portion is this value, and the other side of the polygon
is the 'y' value ('x' if no 'y' provided). If 'NA' (the default), then
this is ignored, otherwise if this is numeric then a polygon is
created instead (and 'type' is ignored). Note that if 'polymin' is in
the middle of the 'y' values, it will generate up/down polygons.}

\item{minmax, min, max}{Arguments passed to \code{points} to highlight minimum
and maximum values in \code{spec_line}. If \code{min} or \code{max} are \code{NULL}, they
default to the value of \code{minmax}. Set to an empty \code{list()} to disable.}

\item{dir}{Directory of where the images will be saved.}

\item{file}{File name. If not provided, a random name will be used}

\item{file_type}{Graphic device. Support \code{png} or \code{svg}. SVG is recommended
for HTML output.}

\item{...}{extra parameters passing to \code{plot}}
}
\description{
These functions helps you quickly generate sets of sparkline
style plots using base R plotting system. Currently, we support histogram,
boxplot, and line. You can use them together with \code{column_spec} to
generate inline plot in tables. By default, this function will save images
in a folder called "kableExtra" and return the address of the file.
