 \description{
 These functions helps you quickly generate sets of sparkline
 style plots using base R plotting system. Currently, we support histogram
-and boxplot. You can use them together with \code{column_spec} to
+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.
