[R] OT: a weighted rank-based, non-paired test statistic ?

[Dylan Beaudette]

Hi,

Is anyone aware of a rank-based, non-paired test such as the Krustal-Wallis, 
that can accommodate weights?

Alternatively, would it make sense to simulate a dataset by duplicating 
observations in proportion to their weight, and then using the Krustal-Wallis 
test?

thanks!
Dylan
