Dear list,
Learning to use the power of R's indexing and functios like head() and
tail() (which are just syntactic sugar) will probably lead you not to miss
this.
However, how do I exclude the last columns of a data.frame or matrix (or, in
general, head and tail for given dimensions of an array)?
I.e. something nicer than
t (head (t (x), -n))
for excluding the last n columns of matrix x
THX, Claudia
