For porting some (time series related) software from S-plus,
I need  solve() {i.e.  solve.qr() }  to work with complex matrices.

I have had a similar request for this from a local user a while back already.
Till R-1.x.y {at least x=y=0} we have had complex Linpack and BLAS in R's 
sources src/appl/z*.f  but never had an R interface anyway and subsequently
have dropped it.

Should we have a package or a `module' (new in R-1.3) 
for providing complex linear algebra in R?
Has anyone done some of the work already?
R-devel readers, thanks for your  support!
