closeAllConnections() in spgrass6. Side effect?

Hi Roger and the others,

I've noticed that readRAST6() uses closeAllConnection(), as it is trying
to close a raw "socket" type connection I had opened for parallel
processing (snow package).

Isn't this a side effect and perhaps closeAllConnection() should be
replaced here by any other alternative?

Thanks (also for the package) and best regards,

Javier,

Could you try a change in the package source from sourceforge, check out 
the CVS source from:

cvs -z3 \
-d:pserver:anonymous at r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial co \
-P spgrass6

I've added a flag to permit the call to closeAllConnections() to be 
avoided; you would use close_OK=FALSE. For most users it is still needed, 
as the number of connections opened in trying to guess what the GDAL GRASS 
plugin needs is not well-specified.

Hope this helps,

Roger

Javier
