[R] 'R' library for Rasch modelling?

[Patrick McKnight]

Bill,

A colleague and I are working on a project that would offer both Rasch
and IRT item parameters estimation along with fit statistics. 
Additionally, I wrote S/R code to produce all classical test theory
(true score model) statistics.  The project is somewhat in its infancy
but you can find the C++ code and some initial code files on sourceforge
and CVS repositories.  We are both extremely busy so progress has been
slow.  If you have any programming expertise in R, we would encourage
you to contribute to the project where you can.  Please find the project
at the following URL:

http://sourceforge.net/projects/ssm/

Cheers,

Patrick

I'm new to 'R', so forgive me if I've used the wrong term.

I'd like to model some Likert-style items using Rasch methods.

I've been unable to find mention of these for 'R'. Would someone happen
to
know of any?

Thanks in any case.

Bill
