Installing and configuring Git

RStudio version control functionality is provided by another software called git

Install git

Git is one of the most popular version control systems in the world. It is free and open source.

• Windows & OS X: http://git-scm.com/downloads
  • Windows: download the .exe file, run it and accept all the default settings (unless you know what you are doing) and keep clicking ‘next’
  • OS X: at the link above, select the first option that suggests to install git through installing homebrew, by pasting a line of command provided in their instructions in your terminal, and accept the prompts appearing in your terminal.
• Debian/Ubuntu: sudo apt-get install git-core
• Fedora/RedHat: sudo yum install git-core

Configure git

After installing git, you need to tell it who you are.

By default, git is used through a command line interface. We’ll use git in this way now in order to perform its initial and minimal configuration. In the remaining of this tutorial, you’ll learn how to use git through Rstudio instead of a command line interface.

On windows, open Git Bash (start menu -> Git Bash). On MacOS, open the Terminal app. On Linux, open your distribution’s (or any other) terminal emulator. Enter the following commands EXACTLY (spaces and quotation marks included) one after the other (hitting ENTER after each command). On successful completion, you should see no output from these commands.

Make sure to replace you@youremail.com and Your Name by your email address and your name.

git config --global user.email "you@youremail.com"
git config --global user.name "Your Name"
