[R] Error in pruning hclust object using maptree package

[Keith]

My bad.

I did read the help. However, I didn't pay enough attention to the data 
argument, and it seems it doesn't need to use data argument in the 
earlier version.

I also noticed this argument afterwards. Now it works for me as well. 
Thanks a lot.
