Dear all,

I'm trying to process HUGE datasets with R. It's very fast, but I would like to optimize it a bit more, by focusing one one column at time..... say file is 1GB big and has 100 columns..... In order to prevent "out of memory" problems.... I need to load one column at the time.... the only problem is that read.table doesn't support this feature....

Is there some thick which will do the magic?

Thank you in advance.
