R help - Oct 2009 - Planned comparisons among means with WRS package

Hello,

I have done a robust two-way ANOVA with the WRS (Wilcox's Robust
Statistics) package. I was also interested in doing a planned
comparison among means, but my knowledge of statistics is quite
limited, and I don't know if a "robust version" for a planned
comparison of means exists. If it exists, I don't know how could I do
it with R. 

Could anyone help me with this? 

Thank you in advance for your help, 

Ana
