Hi Everyone,
I am a little new to R and the first problem I am facing is the dilemma
whether R is suitable for files of size 2 GB's and slightly more then 2
Million rows. When I try importing the data using read.table, it seems to
take forever and I have to cancel the command. Are there any special
techniques or methods which i can use or some tricks of the game that I
should keep in mind in order to be able to do data analysis on such large
files using R?
Specifying the type of each column with colClasses will speed up
read.table a lot in a big file.
You have a lot of data, so having a lot of memory will help. You may
want to work in 64 bit R, which has access to a lot more than 32 bit R sees.
