[R] Create variable with AND IF statement

[Richard Kolodziej]

Hello,

thanks for the quick answers! Some answers were more useful to me than
others but I really appreciate everybodys effort, reading and
answering my question.

I will try Dons approach because as he said, it looks quite readable.
I'll need to take a closer look on the nested ifelse statements to
understand and use them.

What I learned from asking this question is, that I should have stated
my problem far more precisely. I should have shown you what I tried
and what error messages appeared.

Thanks everybody,
Richard
