No subject

Hello to all

Recently I came across a problem. I have to analyze a large survey 
data - something about 600 columns and 10000 rows (tab-delimited file 
with names in the header). I was able do import the data into an 
object, but there is no more memory left.

Is there a way to import the data column by column? I have to analyze 
the whole data, but only two variables at a time.

thank in advance
