How to read large file
Try putting "memory limit linux" or "mem.limits" in the nabble help. Or type ?mem.limits in the R gui. Also have a look at: http://www.nabble.com/RAM%2C-swap%2C-Error%3A-cannot-allocate-vector-of-size%2C-Linux%3A-tt11680213.html#a11680213 Think you also need to check / understand how R deals with what you want to do so you know how many copies of the data it will need to hold in memory. Hope that helps, Darren

Dear all, I want to read a 1.2 G file with 136,736,218 numbers with scan function, and then want make a histogram with those numbers, but it showed Error: cannot allocate vector of size 2.0 Gb. How can I import the file then? The version I used:
sessionInfo()
R version 2.8.1 (2008-12-22) i686-pc-linux-gnu
mem.limits()
nsize vsize NA NA and the computer I use has 4G memory in total. Thank you very much! Dongyan Song
