Large Data Set Help
I am attempting to perform some simple data manipulation on a large data
set. I have a snippet of the whole data set, and my small snippet is 2GB in
CSV.
Is there a way I can read my csv, select a few columns, and write it to an
output file in real time? This is what I do right now to a small test file:
data <- read.csv('data.csv', header = FALSE)
data_filter <- data[c(1,3,4)]
