This can be done by using the width argument inside the stat_boxplot function of ggplot2 package. Instead, each one of the subsequent curves are plotted using points() and lines() functions, whose calls are similar to the plot(). mapping: Set of aesthetic mappings created by aes() or aes_().. data: The data to be displayed in this layer. A neat trick is using the library reshape2 which is a very useful data manipulation library for R. With the help of melt function of this library, we can combine our data into a single data frame in the format that ggplot2 wants from us in order to draw different lines over the same axis.
