Dhiman -
You don't say what you want the result to be if the
value is in both S1 and S2, but here's an example that
may give you some ideas:
S1 = c('one','two','three')
S2 = c('four','five','six')
test = c('one','two','three','four','five','six','seven')
test %in% S1 + 2 * test %in% S2
[1]
Hi:
Try this:
S1 <- sample(10001:98999, 1000)
S2 <- sample(10001:98999, 1000)
> intersect(S1, S2) # lists have some overlap
[1] 72484 82292 93508 50438 29603 28965 68063 79598 16497 43016 22119
# test list
x <- sample(10001:98999, 1000)
# tests first if x is in S1; if not, test whether it's i
Hi,
i think %in% will do exactly what you want
eg.
5 %in% 1:10

?ifelse# handles vectors, while if() handles single values
?'%in%'# also see match() and which()
Enjoy the day,

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
5 matches
