Question

How to read a large gzip tsv or csv file in R?

Answer 1

You can use fread() function of data.table library to read a gzip tsv file.

library(data.table)
v = fread(filename, sep="\t")

If the file has header, you can try the following code:

library(data.table)
v = fread(filename, sep="\t", header=TRUE)
