Some time ago, since I was able to use R by myself, have found some fellows and other people who wanted to learn R as well. Then I pointed them to help pages, to CRAN repositories… but in some cases they said that didn’t know how to start using those resources. Obviously, the main self-perceived limitation for non-programmers is the use of “commands” -ok, many of the 80’s kids will remember the use of some command lines to access games such as PacMan, Frogger… 🙂

At the same time, they also wanted to refresh some basic statistics, acquiring a general knowledge of their data before asking for a statistician’s help. An idea to quickly help them was to make some scripts to guide them through basic commands, seeing results on real-time, and being able to recycle them for their own data.

If you have just started using R, maybe they can be useful for you. However, I will recommend that you use some open “plain text” file(s) to paste your favorite commands and clone/modify them to suit your needs. Remember to store the files where you can access them later!

Tip: you can change the extension of your “mytext.txt” file into mytext.R file, telling Windows to open it with the Notepad again. It will be also a plain text document, but some text editors will recognize it as an “R script” and will highlight the content according to that.

Apart from the Notepad in Windows, you also have a bunch of other text/code editors which are more pleasant to use. See for example R-Studio and Notepad ++.

Copy the Gists below into your own text files, and begin playing with R!
