Because of a keynote at useR! in Vienna this summer on psychometrics
(and sociometrics, econometrics, educometrics, and so on) in R
I have been writing code rather frantically for multidimensional
scaling, correspondence analysis, and logit/probit multidimensional IRT
models. You can find the code at


or at my homepage


Eventually this will be packaged in the appropriate way and documented
(dream on, Jan) but it may be useful to some already in its present
