\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{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.
