Unit 1: Intro - Downloading and Installing R

In this video, we look at how to download and install and run R, our (free) statistics platform.

We also look at some basic statistics:

Review and commments on video 1:

Note that the version of R installed in the video dates from 2014. We regularly check to make sure that all we say remains valid, so the same things remain true for the version 2020.

In my opinion, the documentation for R is bad. If you already know R, the documentation is ok - just ok. Every time I am away from R for a while and come back, my learning curve is just as steep as the first (many) times. So, this website is for me as much as it is for you. I want to be able to get into R as quickly as I can, remember the basic basics and get up and running as fast as possible -- with things that work. Because of the inadequacy of the R documentation for learning, there are many books on the market. But the majority are very expensive and the quality is unknown before buying, and then it may be too late. I'll stop complaining there. I hope this first video helps you get started.

The important thing is to remember the R website - so here it is: https://cran.r-project.org/

The next most important thing is: once R is installed, where is it going to go to get and store my things (files, etc.). This is called the workspace, or the work directory. From the command line in R, you can get it by typing getwd() . Under "files" you will find a place to click to change the workspace to be whereever you want it to be.

Please come back to this site soon. The content will be growing daily...
