In the process of installing and getting the packages sp and rgdal running in my RStudio Version 0.98.501 on my Mac OS X 10_7_5, I get this error message:
Error: This is R 2.11.1, package 'rgdal' needs >= 2.14.0
However if I look at on the RStudio website the version 0.98.501 is the latest and should be up to date with R 2.14. Do I need to de-install any old versions? How would I do that?
