Peter,
Look for 'comma-separated list' on the help page!!
Yes, seeing the solution I also understand why list is the solution.
The special meaning of list () in plotmath was only in my passive vocabulary -
and after this discussion I think it is upgraded to active ;-)
I have to admit that my coming from matlab (as opposed to lisp) still catches me
once in a while: though I was aware that I would somehow need to change the tree
of the expression, I went astray because c() still feels to me the more basic
function to put things together than list ().
A second aspect that put me a bit off the track is that both create expressions
that do have a meaning but don't mean in R what I want to express:
Z [c(a, b)] is meaningful, but not the same as Z [a, b]
Z [list (a, b)] is syntactically correct, but `[.matrix` doesn't accept lists
for parameter i)
Anyways, thanks a lot for the patience everyone:
problem is solved, solutions (including bquote) are to be found in the Wiki, and
instead of creating more fuss by unclear emails I'll fetch a coffee before I go
on plotting my confusion matrix elements...
