I am using xtable version 1.7-1 built for R 3.0.1 on:
R version 3.0.1 (2013-05-16)
Platform: i686-pc-linux-gnu (32-bit)
Sometimes, not every time, when I load xtable or attempt to load the
help, I get an error such as this "Error: cannot allocate vector of
size 1.9 Gb" (Stacktrace from recover() below).
Other times, when loading packages that depend on xtable, I get an
error such as this:
Loading required namespace: xtable
Error in assign(identifier, list(name, description, identifier, help, :
lazy-load database 'P' is corrupt
I have attempted to reinstall the package using
install.packages("xtable", type="source"), but the error persists (and
the xtable.rdb file is identical).
I have also tried this on macs and gotten the same error.
Thank you for any help.

?xtable
Error: cannot allocate vector of size 1.9 Gb
I would guess this is not related to the xtable help page, but is a sign
of something being corrupted (e.g. an out of range write in memory), and
this is just a symptom of the corruption.
If we could make this reliably reproducible, we could track it down, but
without that, it is nearly impossible.
Could try starting an empty R session (nothing reloaded from .Rdata),
run until you trigger the error, then save the session history? See if
replaying that history triggers the error again in the same place. If
so, see if you can shrink it to a minimal script that others can try,
and post that.
