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.


I promise I’ll never go back to read.table again!
