  I think not.
  I believe the only way to do this (it may have been discussed before)
is to use options(warning=2) to promote warnings to errors, then to use
tryCatch() etc. to intercept the errors and store the information somewhere.


  I've added a bit on this to http://glmm.wikidot.com/faq, since it's
not the first time it has come up ...
