Jos had e-mailed me that he found a fix to this problem (after he had
originally asked me, and I sent him to R-help/ the package maintainer), so
I thought of keeping this thread updated with his reply:
After Jos communicated with the maintainers about this, the fix is to
install the raster package from here:
install.packages("raster",
repos="http://R-Forge.R-project.org<http://r-forge.r-project.org/>
")
It is a development version but it got installed on his machine without
glitches and after that it started working.
With regards,
Tal
