Hi,

 

I am trying to read a tab-delimited file into R (Ver. 2.8). The machine I am using is 64bit Linux with 16 GB.

The file is basically a matrix(~600x700000) and as large as 3GB.

 

The read.delim() ran extremely slow (hours) even with a subset of the file (31 MB with 6x700000)

I monitored the memory usage, and found it constantly only took less than 1% of 16GB memory.

Does read.delim() have difficulty to read files with lots of columns?

Any suggestions?

 

Thanks,

Mike
