Dear List, I am trying to read some files using read.csv and total size of those files are 3.99 GB. I am using MacBook Pro with 4GB RAM(snow leopard). I also tried to run a chunk from those files and altogether the size was 1.33 GB. But every time I was getting the following error
R(1200) malloc: *** mmap(size=16777216) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug I managed to run smaller chunks (400MB) and I also saved the object. But problem is when I try to load some of those objects(which is not more than 1.5 GB altogether), I get same error again. Can someone please help? why am I getting this error? does R need more space than the actual file size? I may buy new machine if its something related to RAM size. but if it is some R problem then it will be very useless to buy new machine. So, I really need to know why this is happening. Any help is appreciated. Thanks in advance. regards, Shyamasree ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
