R help - Sep 2009 - Overview of error and warning messages for teaching + examples

Dear all,

The background: as I didn't find a manual specifically directed
towards debugging R code on a novice and intermediate level, I decided
to write a student manual myself. I have some basic examples of errors
(the classical interpunction and writing mistakes), but have the
feeling that I miss quite some of the frequently occuring mistakes and
messages. Therefore I'm looking around to find a list of these, and if
possible, some examples of wrong R code.

I have been googling around a bit, but I couldn't find an overview of
the most common error and warning messages in R. Off course this
mailing list is an extensive source of all kind or errors and
examples, but I was wondering if there is a somewhat more structured
overview. All help appreciated.

Kind regards
Joris Meys

Hi Joris.

This is a wonderlful idea.
I never came across such a document, but assembaling it sounds very good.

What do you think about organizing the work of collecting (by R members and
maybe your students) the error massages and code into some wiki page? (maybe
on the R wiki)

It could be a great work to give to students (go around the mailing list,
search for "i got this error massage", and write what the
code-problem-solution was).


Best,
Tal
