[R] eRm/raschsampler error message

[KD]

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

and receive error message as follows.

"Error in m[idx1, idx2] <- 1 : subscript out of bounds"

Using the same code for a different dataset does not cause this problem.

Any suggestions much appreciated!

(ctr spec:
        burn_in =  100
        n_eff =  1000
        step =  16
        seed =  0
        tfixed =  FALSE )
