[R] problem with parse
Hi there again, I have a problem with the parse-command. First of all, I show you in a simplified way, what I am trying to do and what R answers: test [1] u.g$par1, u.g$par2 mode(test) [1] character ausdruck - parse(text = test) Error in parse(file, n, text, prompt) : syntax error in u.g$par1, That is what I did and I can't find the mistake. I just want to have test without quotes (to do eval(ausdruck) later) but somehow it doesn't work. Is there anything I have overlooked? Can't I put special characters like $ or , into this test-character? Thanks a lot for your help.

Re: [R] problem with parse
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. Regards, Marc -- Dipl. Inform. Med.
