[R] bug Rcmdr

[John Fox]

Dear Richard and Jeremy,

I suspect this is coming from how assignments are handled, and may be hard
to fix. I'll take a look.

Oddly, I can't duplicate this error when the commands are entered on a
single line separated by semicolons; then I get the error message

	unexpected ';' in "withVisible( a <- 2;"

both under Windows and Ubuntu (R 2.6.1, Rcmdr 2.3-10 in both OSes).

Thanks for the information. I'll see what I can do.

John
