Hi there,
I have something that appears to be a factor called drug:
Typeof(drug) => Integer
As.numeric(drug) gives a long list
Levels(drug) gives a long list, too.
Now I want something like the summary function does:
I want to count how often each level occurs in the given vector.
My problem is that summary gives me a list with counts that is incomplete
and adds the "Others" category.
Is there a way to get a count for all levels?
Thanks,
Bernd
