Ok, I confess.
Until yesterday I was one of those still trying to read large data tables using read.table.
Then, I came across this thread in stackoverflow and I saw the light.
Since I noticed that a lot of people still struggle with read.table I decided to write this very brief post.
Imagine that you have your large file named “mylargefile.txt”. Then all you have to do is the following.
library(data.table)
mydata<-fread("mylargefile.txt")
I promise I’ll never go back to read.table again!
