[rkward-users] Variable Class and IRT

[Craig Johnson]

New user to R and RkWard so I'm trying to work through things.  One of the
things I'm trying to do is play around with the IRT features.  The problem
I'm having is that I don't have the proper "class" to run the statistics.  I
can change the variable type (integer, factor, string, etc) but I can't
figure out how to change the class.  Any suggestions would be helpful.

Thanks!
