How to install R

For simulation we are going to use R, a statistical programming language. The software is open-source, interacts well with git, has many packages written by and for the bioinformatics community and is also useful for developing graphics and web app.

We are going to access R via a package called RStudio, which provides additional resources including a window system which facilitates installing packages , accessing the help files, and documenting your work. RStudio is also free.

All of this software is available on Macs, Windows, and Linux. Mostly it works identically on all types of computers, although I have noticed that sometimes the versions are out of sync.

To get started, please install R and RStudio as directed below.

Installing R

  1. Go to

  2. Select a CRAN mirror. (This is the computer that you are downloading from. It is advisable to select a mirror that is geographically close.)

  3. Select the appropriate version for the type of computer you are using.

  4. Install the downloaded software just like any other software on your computer.

Installing RStudio

  1. Go to

  2. Click on the Download button.

  3. Scroll down to "Download R Studio Desktop".

  4. Select the appropriate installer.

  5. Install the downloaded software.

Check the download

Click on the R Studio icon. This should open R Studio.


Install a text editor

Microsoft Word is NOT a text editor. Using Word to edit text will will eventually cause (devious) errors. Best if you start using a proper text editor. Essential features:


Personal preference :

Install pandoc

Pandoc can convert documents across formats: markdown to html or pdf etc.

On Mac OSX:

brew install pandoc

On windows visit the Pandoc website.
