issue creating a subset
I'm performing item response theory with eRm packages
I am excluding the persons that doesn't fit in the infit/outfit persons.
for that I created a condition. then I have to create a new subset or
matrix but with the condition.
So:
ORIGINAL
matrix<-cbind(item1, item2, item3, item4)
IF I PERFORM A head(matrix)
item1 item2 item3 item4
3 2 3 1
3 1
