[R] How to extract every nth element from a vector

[Barry Cooke]

R-helpers:

Is there a simple way to extract every nth element from a very long vector?

[The vector I want to sample from is an object returned by lowess(). It is
so long (11,628 pairs of elements) that it is causing non-R-related memory
problems elsewhere. I don't see a better way other than sampling the output
returned from lowess.]

Thanks in advance.
