read.table freezes the computer
-----Original Message-----
I have a txt file to read into R. The size of it is about 500MB.
This txt file is produced by calling write.table(M, file =
"xxx.txt"), where M is a large matrix After running MM =
read.table("xxx.txt"), the R gui keeps a cpu core/thread
fully occupied forever.
64 bit R with 16GB RAM on Win7 64, i5 cpu should be capable.
So if anyone knows the reason, that will be appreciated.
Thank you for any advice.
A look at the ?read.table section on 'memory usage' may help.
In particular, specifying colClasses as numeric is recommended.
