Can you find a simple example, preferably obtained either from a
simple simulation or from a minor modification of an example included in
some of the standard documentation. This listserve sometimes refuses to
accept attachments, so I would not suggest you attach a data set unless
it was quite small. You could, for example, try reducing the size of
your data set, e.g., using a binary search to find the smallest number
of observations that would still generate the same error message.
Alternatively, the posting guide
(www.R-project.org/posting-guide.html) includes the following:
'When providing examples, it is best to give an R command that
constructs the data, as in the matrix() expression above. For more
complicated data structures, dump("x", file=stdout()) will print an
expression that will recreate the object x.'
Have you tried walking

I know I've discussed this issue on this listserve before.
Therefore, I tried RSiteSearch("graves debug"). This produced 77 hits,
many of which were not relevant. The following seemed to be:
"http://finzi.psych.upenn.edu/R/Rhelp02a/archive/68215.html";.
