R software

In this nearly 6-hour tutorial you will learn menu-based R libraries so you can use R without having to fuss with R code. These libraries don’t cover everything R can do, but they do quite a bit and can set you up to make running R much easier.

You have probably noticed I’m not much into R (though I’m slowly coming around to it).  It goes back to when I was in my graduate statistics program, where we were required to use SPlus (R’s parent language—as far as I can tell, it’s the same thing, but with customer support).

We were given a half hour tutorial and an incomprehensible text, and sent off to figure it out how to use SPlus on graduate level stats.

Not fun.

And since I was already fluent in SAS, SPSS, and BMDP (may it rest in peace), I resisted SPlus.  A lot.

A new version of Amelia II, a free package for multiple imputation, has just been released today.  Amelia II is available in two versions.  One is part of R, and the other, AmeliaView, is a GUI package that does not require any knowledge of the R programming language.  They both use the same underlying algorithms and both require having R installed.

At the Amelia II website, you can download Amelia II (did I mention it’s free?!), download R, get the very useful User’s Guide, join the Amelia listserve, and get information about multiple imputation.

If you want to learn more about multiple imputation:

• Read more articles on StatChat
• Watch my webinar on Approaches to Missing Data
• Get the list of recommended resources.  There are some really good, easy to read articles, books, and websites in this list.
