R help - Nov 2010 - error message: "is"

Hello.

using the lm command, I always receive the error message "couldn't find
the function "is"". Do you haven an idea, what that means?

Thanks for your help.

Best regards.
Kathrin L.

Try adding the line
   library("methods")
before calling lm().  (I've heard that some front-ends
for R do not load the methods package by default.)

Hi Kathrin,

Can you provide:

1) the results of sessionInfo() on your system
2) a copy of the code from the R console leading up to and including
the error message?  For example the exact lm() call, and if possible
some example data that you could use in the lm() call.

Sincerely,


Josh

With that limited information I fear that no one can really help you. 
Please read the posting guide (link at the bottom of each mail) and 
include your code with which we can reproduce your error. Only then we 
can guess what causes this problem. For now I can only guess that you 
spelled some command incorrectly.
