[R-sig-Geo] Passing a parameter from R to r.mapcalc ?

[Agustin Lobo]

Hi!

I have an script in R that mostly controls the
flow of grass commands through system()
I've got stuck at:

for (k in mistat[,1]){
		system("r.mapcalc 'mancha = if(manchas.clmp==k,1,0)'")


is there any way I could pass the value of k to r.mapcalc?
I was thinking on using the shell through system, something like
for (k in mistat[,1]){
		system("set k = @1")
		system("r.mapcalc 'mancha = if(manchas.clmp==$k,1,0)'")

but do not get thru,
(perhaps I'm mixing my memories of the csh and the Bourne shell...)

any help?

Agus
