data.table Getting started with data.table Installation and setup


Example

Install the stable release from CRAN:

install.packages("data.table")       

Or the development version from github:

install.packages("data.table", type = "source", 
  repos = "http://Rdatatable.github.io/data.table")

To revert from devel to CRAN, the current version must first be removed:

remove.packages("data.table")
install.packages("data.table")

Visit the website for full installation instructions and the latest version numbers.

Using the package

Usually you will want to load the package and all of its functions with a line like

library(data.table)

If you only need one or two functions, you can refer to them like data.table::fread instead.
