Installing ggplot “package ‘ggplot’ is not available” and “subscript out of bounds” errors

You have the name of the package wrong - it is now ggplot2 following a major rewrite by Hadley some years ago. I presume the old ggplot package has been removed from CRAN.

install.packages("ggplot2", dependencies = TRUE)

This is what I get:

R> install.packages("ggplot2", dependencies = TRUE)
