This is fixed now in R-devel.
Meanwhile a similar issue was found with \kbd in a \value{} preamble,
but only in Perl 5.10.x (and the same fix resolves that).

This is not a bug. You forgot to use the header=TRUE argument to read.table(),
so your variables weren't recognized as numeric.
Please don't use r-bugs unless you are sure there is a bug in R. Use r-help to
ask for help.

Dear list,
It seems that S4 methods defined for an S3 'base' generic
are not used in 'base' functions.
This can be problematic when 'base' functions start with
something like 'as.matrix'.

The short answer is because S3 method dispatch knows nothing about S4
methods and never has (but maybe should). You select S4 methods by
creating and calling an S4 generic outside of base, and base functions
don't call it.
Details:
Your assertion is not entirely correct. As always, you
Could you send me your package code, off-list. I think the problem may

Hi everybody,
Google has accepted the R-Foundation as mentoring organization
for the Summer of Code 2009. Jippi!
Thus, the idea for the next few days (18.-23.) is that Would-be
student participants discuss application ideas with mentoring
organizations (our collected ideas or their new ideas).
