What do you mean with ,,function'' in the above? But you may easily change
the names of the components of test. Use the fact, that the variable names
in a data.frame (and in a matrix too) are store as the second component in
the list dimnames(TEST). So you could try e.g.
dimnames(TEST)[][length(dimnames(TEST)[]) <- "PoxMean"
