response.pattern and data.frame

[Dr. Hans Hansen]

dear phil

when i pass a data.frame to the response.pattern option of fscores, the result is too long and i guess, there is some duplication going on. i feel a data.frame should yield the same results as a matrix?

best wishes, felix


mod <- mirt(Science, 1)
fscores(mod, response.pattern=data.frame(matrix(c(1,2,1,3,1,2,3,1),2,4)), full.scores=TRUE)
fscores(mod, response.pattern=matrix(c(1,2,1,3,1,2,3,1),2,4), full.scores=TRUE)

You're right, there should also be support for inputting data.frame objects since generally that's how analysts store their data. It's been patched. Thanks for the report!

Phil
