[GRASS-dev] Plan to build Package to use GRASS from R

[Rainer M Krug]

Hi

Sorry for crossposting, but I think this can be of interest for GRASS and R
users.

I am planning to write a package to make the use of GRASS from R easier. The
idea is to wrap the system call to execute the GRASS command into an R
command of the same name.
e.g:
r.to.vect <- function(..., intern=TRUE, ignore.stderr=FALSE)
  {
    comm <- paste( "r.to.vect ", ..., sep="" )
    print(comm)
    system( comm, intern=intern, ignore.stderr=ignore.stderr )
  }

My questions are:

1) Is this a good way of doing it, or is giving a named list to the function
more usefull?
2) Is there a way to obtain easily all commands from GRASS and the
parameters possible and required?

Any ideas and comments welcome,

Rainer
