[R] read.table() 1Gb text dataframe

[Stephen HK Wong]

Dear All,

I have a table of 4 columns and many millions rows separated by tab-delimited. I don't have enough memory to read.table in that 1 Gb file. And actually I have 12 text files like that. Is there a way that I can just randomly read.table() in 10% of rows ? I was able to do that using colbycol package, but it is not not available. Many thanks!!
