Thanks Jeff:
I simplified my code and a single line in which I open a file causes
this problem. The file opens well in another program and smaller files
open just fine in R. So it seems the problem is with a default value
somewhere for how big the files can be. I am suspicious of this as R
crashes within a millisecond from running the line that tries to open
the file. Anyway, I wanted to provide this info in case you may know
what could be causing this Runtime error in r.
Thanks,
Camilo

Quoting Jeff Newmiller <jdnew...@dcn.davis.ca.us>:
It would seem that in going to a 64 bit architecture you have not
escaped your memory problems. Such problems are highly varied in
details, so you would need to be much more specific about how you
are encountering this problem before anyone could help. Read the
Posting Guide and make a reproducible example and provide the output
of sessionInfo just before the problem occurs.
Note that operating-system-specific solutions are sometimes
necessary, but algorithmic solutions are usually the most powerful
at scaling to larger sizes... that is, change your code or use a
different tool for part or all of the work. It can become crucial to
understand every step of the processing you are doing in such cases.

Hi everyone:
I am running a code in R and I get the following message after using
large files (files larger than 2GB):
"Runtime error!
this application has requested the Runtime to terminate it in an usual
way.
Please contact the application's support team for more information"
Another person posted a similar situation years back with the use of a
large data.table. but no solution was proposed. Does anyone has come
across this problem? is there a fix?.
in R at 64bit, the message appear immediately after running the code.
At 32bit, the code start but I run into the issue that the code
reaches the RAM limit. This makes me to suspect that the error in
64bit is related to a default value on how big the files could be.
Anyway, any help will be highly appreciated.
Cheers,
Camilo
