Since ggplot2 is based on grid-graphics you should also search on 'grid table text' in the usual places and with the usual tools. My favorite search engine for the Archives is Markmail and my search tool for CRAN functions is sos::findFn. I'm pretty sure that Baptiste Augie has written a function or a package to do this, and I've seen several worked examples on StackOverflow. This is something I fairly quickly found:
