[GRASS-stats] R-GRASS error: "all connections are in use"

[Juan Manuel Barreneche]

Hello list,

I'm currently using R version 2.5.0 (2007-04-23) in conjunction with
GRASS6.2.2.

My goal is to use a loop to extract data from rasters created in grass
(a different raster in each simulation, created with r.cost using a
unique cost surface raster, which is deleted every time in order to
free disk space).

Error in file(paste(fname, "wld", sep = "."), "r") :
         all connections are in use

In addition, after this message every time i try a help comand (such
as ?file, ?rbind, etc...) i get the same message:
Error in file(con, "r"): all connections are in use

I've been working with R and GRASS for about 9 months and I'm not much
of a specialist, so i'm really lost here, does anybody have a clue
about the solution of this problem?

many thanks,

Juan Manuel
