I used fread() function provided by data.table package to read csv file.
I got the following error when I tried to read a large csv file (about 5GB).
Error in fread(fileName, header = FALSE, data.table = FALSE) : Opened file ok, obtained its size on disk (0.0MB), but couldn't memory map it. This is a 64bit machine so this is surprising. Please report to datatable-help.
It’s ok when I use smaller file (about 1GB).
Do you have any idea to solve this issue?
