Thanx for clarification on stating my problem, Charlie.
I am attempting to merge to files, i.e.:
hi39 = merge(comb[,c("hillID","geo")], hi.h39, by=c("hillID"))
if this is relevant or helps to explain:
the file 'comb' is 3 columns and 1127 rows
the file 'hi.h39' is 5 columns and 19758564 rows
i started a new clean R session in which i was able to read those 2 files
in, but get the following error when i try to merge them:
R(2175) malloc: *** mmap(size=79036416) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
R(2175) malloc: *** mmap(size=79036416) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
R(2175) malloc: *** mmap(size=158068736) failed (error code=12)
*** error: can't allocate region

R(2175) malloc: *** mmap(size=158068736) failed (error code=12)

R(2175) malloc: *** mmap(size=158068736) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Error: cannot allocate vector of size 150.7 Mb
so the final error is "Cannot allocate vector of size 150.7 Mb", as
suggested when R runs out of memory.
i am running R version 2.9.2, on mac os X 10.5 - leopard.
any suggestion on how to increase R's memory on a mac?
thanx for any much needed help!
