Maybe twelve, thirteen, years ago Dietem started this project called r metrics, I do have to say that it has followed very closely a software product that I helped develop for an insightful corporation called Fin Metrics, which was a commercial product that you have to pay for, whereas R Metrics was, and Fin Metrics was based on the commercial S plus programming language which is the commercial version of R. R Metrics is very much like Fin Metrics but is using R instead of S plus. so but one of the things that he, he's done as part of our metrics is to build a very sophisticated suite of portfo, of tools for doing portfolio analysis.
