One way to test the new ggplot2 is to make a new directory to use as an R
library and to install the new ggplot2 there.
   newLibrary <- "C:/tmp/newRLibrary"
   install.packages("ggplot2", lib=newLibrary)
Then you can run two R sessions at once, starting one with
to use the new ggplot2 and the othe without that line to use the old ggpot2.
