Occasionally I’d like to plot a table alongside a chart in R, e.g. to present summary statistics of the graph itself. Thanks to the gridExtra package this is quite straightforward. The function tableGrob creates a table like plot of a data frame, while arrangeGrob allows me to arrange ggplot2, lattice and grid graphical objects (short ‘grobs‘, such as tableGrob) on a page.

Here is a little example:
