R help - Nov 2011 - SPSS -> R

I'm an SPSS user trying to make the transition to R.

Can someone help me translate the following SPSS code into R?:


GLM Total_tp1 Total_tp2 WITH Age Sex
  /WSFACTOR=Time 2 Repeated
  /METHOD=SSTYPE(3)
  /CRITERIA=ALPHA(.05)
  /WSDESIGN= Time
  /DESIGN= Age Sex Age*Sex.

Also. can anyone recommend any resources to help SPSS users learn to things in
R?

Thanks,
-kristi

If you know SPSS already why not learn R modeling syntax and do this
yourself?

If ALPHA(.05) implies that you are using stepwise variable selection note
that this is an invalid statistical technique.

Dear Kristi,

I assume that this is a repeated-measures ANOVA with one within-subjects
factor (Time) and two between-subjects factors (Age and Sex, which are
crossed). If Age is numeric, and not a factor, then the "type-III"
tests
that you requested don't test sensible hypotheses. In any event, if my guess
is right about the design, then you can use the Anova() function in the car
package for an equivalent analysis. See the repeated-measures example in
?Anova (for the O'Brien and Kaiser data). 

You've already had an answer to the more general question.

I hope this helps,
 John

Dear Kristi,

You may want to have a look at the R2STATS package, a simple GUI for 
linear models.
