[Rd] transpose of complex matrices in R

I believe that I have actually (many years ago) used a true complex transpose, but I agree 
that one more often needs the conjugate transpose. I would not be in favour of changing 
t() because I feel transpose means transpose -- certainly where there are non-square 
matrices. But I'd be in favour of adding a conjt() (or some similar function) that does 
the conjugate transpose efficiently.
