The output i want should have the rows reordered along with the dendrogram and the columns should be in the original

[Re-directing to R-help, as this is more appropriate there.] I tried copying the snippet of data into the windows clipboard and tried it: > dat <- read.table("clipboard", header=T) > dat Name Weight Height Gender 1 Anne 150 65 F 2 Rob 160 68 M 3 George 180 65 M 4 Greg 205 69 M > str(dat) `data.frame': 4 obs.

To be more clear, can i
