Thank you, Rolf, for this well-deserved spanking :-)
I promise to amend my ways and think before I send in the future.
Best,
Stephan

Assuming your data are in a data.frame called dataset,
apply(dataset,2,median)
should work. Look at
?apply
Note that apply() works with ***matrices***. The foregoing code will
work, given that all columns of ``dataset'' are numeric, due to the
fact that apply will *coerce* a data frame to a matrix.
However it should always be remembered that
DATA FRAMES ARE NOT MATRICES!!!
cheers,
