I am working with a dataframe creating slices of the population with different characteristics. One of the Columns is a choice of 4 categories of products. There are no NAs there. If I include "!=Prod4" in the subset statement I get count different from if I include "==Prod1|==Prod2|==Prod3".
Any ideas?
