Hi

In older version of the execGRASS function of spgrass6, setting the option
intern=TRUE would make the output of the grass command a R object.

Now, when I run execGRASS with the intern=TRUE, like the statement below,
the output is not written to the R object.

a <- execGRASS("r.univar", flags="g", map=distmod, separator=";",
intern=TRUE)

The object 'a' is created, but it is empty (character(0)). However, when I
set legacyExec=TRUE (like below), the object 'a' is created with the grass
r.univar output.

a <- execGRASS("r.univar", flags="g", map=distmod, separator=";",
legacyExec=TRUE, intern=TRUE)

Is this the intended behaviour (i.e., did I miss something in the help
file)?

I am running R version 3.0.1 (2013-05-16), on Ubuntu 13.04 64-bit

Paulo
