Flexibility is one major advantage of R over SPSS. It also has better
`publication-quality' graphics. It's easier to do simple things in SPSS,
but probably harder to do complicated things.
The available documentation isn't that bad, if you start with
"Introduction to R" and then some of the contributed documentation on
cran.r-project.org. Learning to use statistical procedures that you
understand fairly well is pretty straightforward. Learning to use
procedures you don't understand at all can be much harder, but that might
be regarded as a feature. I'd say that if you can use Linux you should be
able to cope with R.
