Well, thanks to you all, the problem was fixed. It turned out that
RB's suggestion was right (i updated R, only). I apologize for sending
only partial information (in fact it was because of a distraction that
i didn't put all the script, etc. in the email).
One thing caugth my attention though: every time i call readRAST6 a
warning message apears, saying:
warnings()
$`closing unused connection 3 (gsub(" ", ":", l8))`
NULL
I suppose this is exactly the improvement that Roger B. pointed out in
his reply, and i just didn't give much importance to it. Please let me
know if there is something important to take into consideration...
It is just a warning message, nothing more, but in future releases I will
try to get it to go away by opening and closing the connections
explicitly. I had though that more recent versions had fixed the problem,
I don't think that we know what version of spgrass6 you are using.

Thanks again,

Hello list,
I'm currently using R version 2.5.0 (2007-04-23) in conjunction with
GRASS6.2.2.
Please always include the output of sessionInfo(), in addition to the R
version. spgrass6 is updated from time to time, so it may be that you are -
for example - using an obsolete route, although you are using BIL files, so
I guess that this is readRAST6() in a loop, as Jarek suggested.
Specifically, I think that this problem was solved in R-2.6.0 - the
relevant news item is:
o Connections will be closed if there is no R object referring to
them. A warning is issued if this is done, either at garbage
collection or if all the connection slots are in use.
which means that functions do not need to close them explicitly.

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") :

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
