Re: [R] How to read HUGE data sets?

Depending on how many rows you will delete, and if you know in advance which ones they are, one approach is to use the "skip" argument of read.table. If you only need a fraction of the total number of rows this will save a lot of RAM. Mark Mark W. Kimpel MD ** Neuroinformatics *

Paul, Yes, I have manually removed it multiple times and it continues to reappear. I'll try to just upgrade a few packages at a time and see if there is one in particular that is causing the problem. Failing that, I'll run this past my system admin. Thanks for your help, Mark Mark
