Question

I can post more data if you let me know what I should run, but here is the error and the version.

> install.packages("ggplot2", dependencies = TRUE)
Warning in install.packages :
  package ‘ggplot2’ is not available
Installing package(s) into ‘/home/johnny4000/R/x86_64-pc-linux-gnu-library/2.12’

and the version

Answer 1

Two options:

1. Update your verions of R. Version 2.12 is pretty old (this is the option you should go for).
2. If step 1 isn’t possible, then you could try the archived packages, but that may be tricky since you will need all of the associated dependencies.
