### Other

R is a programming language for statistics. However it may have menu-driven versions maybe available R commander we haven't tried that and another one is pmg GTK maybe here

R_Statistics introduces you to R

R reference cheatsheet, also a file here Media:Matlab-python-xref.pdf‎ that gives equivalent code for doing array operations in MATLAB, Python, and R plot parameters

In the lab we have the book Using R for Introductory Statistics.

There is a wiki with some good tips here.

Examining your data matrix or object, let's say it's called datos

```head(datos)
str(datos)
```

Don't use the function attach. It seems to leave lots of data in the 'environment' that can cause problems later. Also it makes the code harder to understand.

### doing ANOVAs etc

I think I had too many error terms reducing error terms

## Dealing with circular data

von Mises vs. wrapped Gaussian,
