covariance
Does anyone know a way to calculate the covariances between two
arrays/matrices x and y, row by row. i.e. var(x[n,],y[n,]) for all n ?

renaming column names
...sage, but the column names don''t change because
when I then type :
colnames(data)
I get the same set of names as before, so the assignment doesnt seem to have
worked.
Any ideas or suggestions gratefully received.
