Parsing problem solved thanks to R-Help mailing list
Recently I had the necessity to parse several HUGE text files (~6M lines ~ 600Mb file size) not formatted in a standard way (so not easy import via scan, read.table etc.).
Because of the size of these files I have to avoid loops and find a way to vectorize my problem.
After several hours spent trying to solve this problem without success, I decided to send an help request to the R-help list. In no time i got the answer to this very problematic (at least for me) exercise :-)
You can read the full story here.
I REALLY love the R-Help mailing list! Thanks Guys!
