During a R session (Version 1.4.1 under Windows) I ended up

gc(), memory.size(), memory.limit(300000000),
?memory.limit says:
Usage: memory.limit(size = NA)
Arguments: size [...] request a new limit, in Mb.
^^
So something like memory.limit(500) is more reasonable,
depending on the
size of RAM in your machine.
It is much more convenient to set --mex-mem-size=500M at the command
line, how it works is described in the R for Windows FAQs.
What could I do now to save my data? How could I prevent
this situation?
a) Be sure a reasonable amount of memory was really allocated.
b) Rewrite your R code to consume less memory and think about what is
needed in memory at one time. Can you divide the computations into
"smaller" ones releted to memory usage?
c) Buy some more RAM.
d) Wait ten years for a much bigger computer. ;-)
