Hello everyone,
I am stuck with an apparently simple issue :
i) I have two sets S1 and S2, each containing a large number of integers,
say zip codes.
ii) Now, I just want to test whether a particular zip code belong to S1 or
S2 or neither of them.
iii) If it belongs to S1, the area/region gets a particular label, say 1; if
it belongs to S2, it gets a label 2 and if it doesnot belong to either S1 or
S2, it gets a label 0.
iv) I have to do this for a large number of zip codes as well.
So I was thinking of embedding it into a if else loop but I am stuck on how
to define the "belongs to" in R syntax. Any hint will be much appreciated.
Best regards,
