Just to add to this: QGIS and R under Linux works as well - But as there seem
to be slight problems with the grass console under QGRIS, I have the following
procedure (QGIS already connected to grass): I start xterm from the grass
console in QGIS and in this console R (or emacs...). Works nicely

Hi Agustin
The short answer is not.
However this mechanism in somewhat in the plans
in something we've called temporalilly "myR"
in the sense of R from my application.
The "inners" would use the same mecanism and possibilities are to
add R capabilities in a customized TerraView and/or call R dire

Oooh, you are giving me ideas!
Very interesting work, Paulo.
Can you display from R on the TerraView window?
I dream with a GIS tool (A GIS display tool for R? An R plugging for
Qgis? etc)
that could display spatial R objects. This is beyond current
tools, based on exporting (hence duplicating space and troubles)

There may be other alternatives, but
this is one of the functionalities in an external software (terralib) that
the aRT package tries to make usage.
The aRT web page has one example:

Hi Peter,
I've been doing this in postgis. Once you get used to it, its not too
difficult. Load data with shp2pgsql (or use rgdal + RODBC or similar
if you want to stay in R) and then create a new table to hold the
results. After that you can do "insert into restab select
buffer(the_geom, dist) fr
Dear R gurus,
I am very excited about all the spatials tools in R because they have
almost liberated me from ESRI products. One of the last things I have
yet to figure out how to do in R is to create buffers around polygons
(or just expand polygons). I searched the R-sig-geo archives (using
Go
