[R] last.warning and Sweave?

[Ben Bolker]

  Sweave does something clever with warnings, which I have so far been
unable to figure out.  There are a couple of threads on the list about
this, but the best in here is a hack to redirect all the output and
stick it back in.

  I thought I could get around this with last.warning , but apparently
that doesn't work -- this file doesn't produce the desired output of
reproducing the last warning ...

  any thoughts?
