[R-sig-Geo] img file

[Nick Matzke]

Thanks!!  I did an update of raster before our previous 
emails, but apaprently it didn't take, even after:

 > rm(list=ls(all=TRUE))
 >
 > Close R&  save workspace (answer = yes)

...what it took was (at Mac Terminal):

==========
   486  cd 
/Library/Frameworks/R.framework/Versions/2.10/Resources/library/
   487  ls
   488  cd raster
   489  ls
   490  cd ..
   491  rm -R raster
   492  ls
==========

(On Mac OS X, R.app gui)

And then in R.app gui:

========
rm(list=ls(all=TRUE))

Restart (save workspace = yes)

Packages --> Package Installer --> Local Source Package --> 
Install --> raster_1.7-18.tgz (downloaded manually from CRAN)
========

So now the below works.  Thanks!  I'm cross-posting to 
r-sig-geo for posterity.

Cheers!
Nick
