I found some weird behaviour and reported it as

error.
The dev.off() function was behaving as documented, but it behaves in an
unexpected (by me) way, and that caused
Hi all,
I noticed that `expand.grid()` has somewhat inconsistent behavior with
dropping `NULL` inputs. In particular, if there is a leading `NULL`,
then it ends up as a column in the resulting data frame, which seems
pretty undesirable. Also, notice in the last example that `Var3` is
used as the
Jan,
have you re-installed all packages? If you change (update) any package that
uses S4 it may be necessary to re-install all its reverse-dependencies as well
since they may include cached values in their namespaces, so the easiest is to
make sure you re-install all packages.
Cheers,

I'm observing that if there were no previously open graphics devices then
your `safe.dev.off()` opens up a new graphics device which may be an
undesired side effect (because "surprisingly" `dev.set()` on the null

Thanks! However, isn't length(dev.list()) == 0 when there are no

it. Although there wouldn't be any

Since the CRAN e-mails quote the R CMD check messages verbatim,
Hello R-devel,
I hope that you are all doing well and that this is the right place to
discuss my somewhat mysterious issue with S4.
On our Ubuntu server, we have "mirt" package installed which defines S4

I was bitten by this recently but fortunately Rolf had beaten me to
writing a question. The one thing which really surprised me is that the
current message tells me how much space it would have saved if it had
compressed the files in which case my immediate response was "Well, why
