Non parametric, repeated-measures, factorial ANOVA

Hi I have data from an experiment that used a repeated-measures factorial 2x2 design (i.e. each participant contributed data to both levels of both factors). I need a non-parametric version of the repeated-measures factorial ANOVA to analyse the data. SPSS only has non-parametric tests for one-way ANOVAs but I have been told that the test I need can be implemented using the R software. Unfortunantly I haven't been able to work out how to do this test in R. I've got the Wilcox book 'Robust Estimation and Hypothesis testing' but to be honest I don't have enough of a background in stats to understand a great deal of it, and I wasn't able to work out how to do the test I want. Can anyone let me know how I can do such a test in R? I presume this is a test that people frequently need to use and that there will be some code already written that can implement the test.
Hi Rob, The nparLD package, based on the work of Professor Brunner, might do what you want. Jim
