[R-gui] Small annoyance while interacting with R

-----BEGIN PGP SIGNED MESSAGE-----

You don't tell us anything about your platform or how
you are creating the R session.
But yes, R is designed when running in non-interactive mode
to quit when there is an error.
There are different things you can do to get the desired
behaviour.  I suggest you send mail to r-devel as this
is not just an R-sig-gui question.

Hello,

I'm trying to write some program in Ruby to interact with the R console but it
doesn't work : in short, I can connect R standard input, output and error and
retrieve correct calculations for correct inputs, but as soon as R writes
something to the standard error, the program exits.

For example

for

stdin : "3 + 3;"
stdout : ">3+3\n" "6\n"

but for
stdin : "a;"
stdout : "Error : object not found\n" "Execution finished"

It doesn't say that when used with the normal shell.
The same program works perfectly with the simple calculator bc. Does anyone
knows of this particularity ?

Pablo
