Hi,
I had experienced some segmentation faults ("SIGSEGV" on Linux) on my
Linux
RH 7.0
box at home, I know and use one, not very clever way:
>save.image(file="foo")
or just>save.image() # to .RData
often enough to prevent loss of large part of work.
Probably the R veterans will give you better advice, but this method was OK
for me.

I'm experiencing segmentation faults from time to time
that abruptely end my R sesion. In such cases, is there
any way to recover the work done? (i.e., is there
any temporal file that I could use?)
Thanks

When there is a segfault, nothing is saved automatically. 1) Do not rely on saving your workspace in R, but keep enough information to reproduce objects as needed. Old-timers expected segfaults frequently (but see below). 2) Segfaults are bugs. If you are not linking in compiled code, they are bugs in one of R, any contributed packages or your OS, so please report them as described in the FAQ. However, given your OS is RH7.0, the third of those possibilities is not unlikely. On a reliable OS, segfaults in R should be rather rare: apart from using package foreign (where a couplke of errors have been corrected recently) I have not seen one for a couple of months at least. -- Brian D.
