[Gvsig_english] gvSIG with R

[G. Allegri]

I forgot to say why I would try this way:

 - The spatial packages to manage spatial objects are very well done,
and have a long experience (sp, rgdal, etc...). I think it's a good
choice to make use of them....
 - They're callebla through R commands: it would be only necessary to
give to R scripting a "way" (thorugh shell?) to relate with gvSIG
environmente, as all the rest of the job has been already done.

Bye
