Hello Antje, > Is there anything I have overlooked? Can't I put special characters > like "$" or "," into this test-character?
If I understand "?parse" correctly, you are supposed to pass a valid R
expression to it and
"u.g$par1, u.g$par2"
is not as the comma is not a valid delimiter here.
However,
> parse(text="u.g$par1; u.g$par2")
expression(u.g$par1, u.g$par2)
does work (note the semicolon instead of the comma) and
might be what you want.

Marc
