Re: [R] Installing RGDAL on CentOS v.6.2

Dear Eric, Thank you for your reply. Unfortunately, I don't have NetBSD on the cluster and considering the size of my dataset, I can't utilise my local machine. Does it make a difference that the R installed on the cluster is up-to-date if I do want to compile everything from tar.gz? Thanks

Re: [R] Installing RGDAL on CentOS v.6.2

Dear Shouro, I should have mentioned that pkgsrc is cross-platform, and not restricted to the NetBSD OS. I use pkgsrc on my CentOS machines to provide up-to-date software. Since sysadmins tend to be conservative about what they will install on computers, I end up installing my own software

Re: [R] Installing RGDAL on CentOS v.6.2

Dear Shouro, I can confirm that I have installed GDAL (and RGDAL) on CentOS 6.4, 6.5, and 6.6. But quite frankly, these systems have such old versions of software that I spent a fair amount of time compiling everything up from tar.gz. This is exhausting, so I spent some time learning
