[R] CPCA?
It would be great to know if and where an R code for Common Principal Component Analysis is available.

The only code I know is in IMSL Fortran library, and that is proprietary, and that is expensive. After a quick look, it really appears that IMSL C library does not have the code, but you got to go to Fortran. Look for function DKPRIN (KPRIN). That code cannot be ported to R, naturally. Another issue is that the code obviously was written by Bernhard Flury, and he also has FORTRAN listing in his book "Commaon Principal Components and Related Multivariate Models" (J. Wiley & Sons, 1988). I don't know of the licensing status of that code. I didn't find any explicit licensing information in the book (but may have overlooked something), apart from the usual book copyright that forbids everything. I assume it is the same code that is the base of DKPRIN in the IMSL FORTRAN library. Would mean a lot of typing at minimum, and for any sensible code, editing the code to use LAPACK where ever possible. Further, Flury descirbes the algorithm in his book, and it could be implemented independently in R. I think nobody has done that (yet). cheers, jari oksanen __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] R-CPCA
Dear Ben Bolker, searching for a R code able to do the CPCA I found a message by you on https://stat.ethz.ch/. In that message you said you have something I am looking for. Would you share with me? I ma stuck with a commercial software (GOLPE) that is not developed anymore, therefore I'd like to try to use R for the calculations I need.

If you send e-mail to bolker ufl.edu, I can send you a copy of the package (not hosted on CRAN for the time being). As far as CPC goes, my package just provides a wrapper for Patrick Phillips' CPC code -- you might try searching for that instead. sincerely Ben Bolker __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
