descript() reports frequencies of all zeros (0 0 0 …) when data contains optional questions #6

When a test contains optional questions descript() returns all zeros for frequencies.

Q1 Q2 Q3 Q4
1 1 1 NA
1 NA 0 1
0 NA 0 1
1 1 NA 1

descript(data, chi.squared=FALSE) returned Frequencies: 0 0 0 0 0 Expected: 0 1 1 2 0
