I've installed the package cPCG with succes, yet my computer(s) will not recognise the functin pcgsolve (the peconditioned conjugate gradient method). Every time I try to use it, it says
Error in pcgsolve(A) : could not find function "pcgsolve"
It comes from this R-page which seems like the propper R documentation http://search.r-project.org/library/cPCG/html/pcgsolve.html
any advice?
