My rgdal version is 2.0-31 (see below) and how the system says my version is 0.7-19? Isn't it interesting?

raster 2.0-31 (9-November-2012)

Error in .requireRgdal(FALSE) : you use rgdal version: 0.7-19
You need version 0.7-22 or higher

Please clarify me if you see whats going on.

sessionInfo() will tell you what's loaded and install.packages("rgdal") in a fresh session will install latest, depending on your system

Mike, I just updated my R (I uninstalled the previous version of R and installed R version 2.15.2). Still, I get the same error message.
