[R] two questions

[Iasonas Lamprianou]

Dear friends, two questions

(1) does anyone know if there are any non-parametric equivalents of the two-way ANOVA in R? I have an ordinal non-normally distributed dependent variable and two factors (gender and city of birth). Normally, one would try a two-way anova, but if R has any non-parametric equivalents, that might be great. 
(2) Also, if the interaction of gender and city of birth is statistically significant, which post-hoc tests should I run?

Thanks

Jason
