[R] rgdal error when trying to import raster

[Ben Tupper]

Hi,

The message "there is no package called 'rgdal'" means that you don't have rgdal installed.

https://cran.r-project.org/web/packages/rgdal/index.html

Also, you will get very good patial-centric help if you subscribed to r-sig-geo here

Cheers,
Ben

I am not using library(rgdal) and none of the other libraries that are loaded require rgdal. The package raster does suggest it though. Is that causing the problem? Is there a way to avoid this? Any help is welcome.
