Hi,
this error message is due to a bug in RaschSampler. I corrected it and sent
it to CRAN. RaschSampler version 0.8-5 should be available from there soon.
Thanks for the hint and please apologize for any inconveniences.

I'm not familiar with eRm but subscript out of bounds often occurs when the
data isn't the structure you think it is. Perhaps your input is not what is
expected - might not be as long/wide as required. Depending on how allb is
stored, you might be flipping rows/columns around? try checking the
dime
Hi, I am running the non-parametric rasch model tests using eRm. I have a
reasonably large dataset for this type of exercise (110 items, 248 persons).
I run:
> allb2=as.matrix(allb)
> rsample <- rsampler(allb2, ctr)
> t102<-NPtest(rsample, method="T10") #global test, subgroup inv
