[R] Help with RGDAL

[Don MacQueen]

I did this recently with a kyngchaos binary build of rgdal, 
rgdal_0.6-12.tgz and R 2.9.2.

I'll assume you have current rgdal binary package file in a directory 
somewhere.
(looks like 0.6-18 is current)

Here is what I did (with version 0.6-12).
Note that I work from the command line, not from the R Gui, but it 
should work either way.

cd to the directory containing the rgdal file.
Start R (type "R" at the command line)
At the R command prompt, give the command

    install.packages( 'rgdal_0.6-12.tgz' , type='binary', repos=NULL)

That should do it, assuming any and all resources required by rgdal 
are already installed, and installed in places where the kyngchaos 
rgdal expects to find them. This is pretty well documented on the 
kyngchaos webpage, and it looks like you've been paying attention to 
that, since you already installed GDAL (the kyngchaos framework build 
of GDAL, right?) The kyngchaos build of rgdal may have other 
requirements besides GDAL, I don't remember.
