I try with:
ret = Shell(exestr)
and it starts R, but the source file is not executed
inside R
> a=commandArgs()
> a
[1] "Rterm" "--restore" "--save" "--args" "2005-02-03" #correct date
passed
[6] "<" "m.in.R" ">" "out.txt"
>
it restores the correct workspace, but then it fails to source the
script, which is located in the same dir as the workspace.
inside R
> source("m.in.R") # does the job, so it is not a finding problem
BTW is it possible to get the error message from R somehow???

This seems to be a VBA problem, not an R problem. Rterm returns a 0
return value when it exits cleanly, and a non-zero value when there's
an
error. It looks as though you're losing that by wrapping the Rterm
call
in a batch file. Can't VBA make the call to Rterm directly?
