R

R is a language for statistical computing and graphics. R's use in the data science and econometrics community has taken off over recent years and (at a bare minimum) should be considered as an open source replacement to Stata.

Installing R for Mac Users

Go to the R homepage and download the installer for your operating system.

The current version for Mac and Windows is R version 3.6.2.

Once you have installed R, verify your install.

Why Not Install via Homebrew?

There is conflicting views on Homebrew's installation of R. Because we haven't tried it to ensure no problems will emerge, we recommend going with the installation based on the CRAN distributed package.

Installing R for Linux & Windows Users

First, we need to add a repository so that our operating system knows where to install the most recent version of R from.

Enter the following into the terminal and press Return:

1	sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'

Now, update to get the package manifests from the new repository:

1	sudo apt-get update

Note: if you are using a different version of Linux or Ubuntu - i.e. not Ubuntu 18.04 LTS, check out this site to correctly modify the entry above.

We can now install R as from the terminal by entering the following:

1	sudo apt-get install r-base r-base-dev

Install the multi-threaded OpenBlas library to get higher performance for linear algebra operations:

1	sudo apt-get install libopenblas-base

Now, verify your install.

R on WSL Ubuntu vs. R on native Windows

Even if you already have a version of R installed on your Windows machine, you need to install R inside the WSL Ubuntu 18.04 environment we have set up. Your Ubuntu terminal cannot see everything you have on your native Windows installation.

Verifying your Install of R - All Users

Open a terminal and enter:

1	R --version

followed by pressing Return. The expected return begins with:

1	R version 3.6.x (2019-xx-xx) -- "Some Funky Name"
