I want to check whether option "K" to a function is an integer, a list of
single numbers, or neither of these, and then to execute one of three
different statements.
If these K were a simple parameter, I could do it with
f[k_Integer] := functionBody;
f[k:{_Integer}..] := functionBody;
f[k_] := functionBody
but I cannot see how to check for similar conditions on an *option* inside
one function. Can anyone help?
