I suggest using the most recent version of R (2.12.0 I believe)
and providing a reproducible example, showing us exactly how you
are creating this data.frame (assuming it still exhibits the
behavior).

Hi,
I'm creating a data frame of 24 columns and 45101 rows.
Here is the error I get:
R(147,0xa04d8720) malloc: *** mmap(size=184320) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Any idea of what I can do to trouble-shoot?
Attached is the session  info:
R version 2.11.1 (2010-05-31)
i386-apple-darwin9.8.0

locale:
[1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base



Thanks in advance,
Anjan
