[R-sig-Geo] Raster analysis using R

Dear Henning,

There has been some discussion recently whether we should be developing raster data processing
capabilities in R (e.g. https://stat.ethz.ch/pipermail/r-sig-geo/2008-June/003785.html), since there
are number of (extensive!) open source GIS packages that can be nicely controlled from R. 

Most of R users under Linux use GRASS for raster map processing:

I've just started writing a small user's guide to run GIS analysis in ILWIS/SAGA:

Have fun,

T. Hengl

Subject: [R-sig-Geo] Raster analysis using R


I was wondering if there are some R packages which deal
with analysis functions on raster inputs.

While reading http://cran.r-project.org/web/views/Spatial.html
I've got the impression that the packages mentioned there
do not provide possibilities on doing for example spatial 
resampling or reclassification on an input raster file like a
(georeferenced) satallite image. 

In the seminar `Geostatistics and Image Analysis' I'm attending
some topics are dealing with the combination of in situ sensor 
data and satallite images or aerophoto respectively.

Is there a discussion on the web, how much R can (or should
be able to) handle raster image data and corresponding
raster analysis?

Best regards
