By default answers are expected to be numeric values. You can change that to character with items.char=TRUE
.
The parameter answ
is quite versatile. You can just feed it your observation data,
if it complies
with the naming scheme for items (Item###
,
see also klausur.gen
), and
klausur.gen.corr
will use all of its items automatically. Or you assign the number of items directly
as an integer value. If you leave answ=NULL
,
you will be asked for the number of items.
