Sorry for the english, I speak in spanish
In social psycology and sociology is usual the use of attitude scales, an example is the Likert type, which is the most common.
This scales must be procesed whith relliability tests, R includes the cronbach alpha in the packages psy and psychometric. And I thing that this procedures will be useful in the RKWard package.
I don't know programation (I'm a sociologist), but if someone want help, I belive that I could be useful.
Thank you for RKWard
