which3

which of three vectors are the elements (all, any) true?

Provides utility functions that are simply, frequently used,
but may require higher performance that what can be obtained from base R.
Incidentally provides support for 'reverse geocoding', such as matching a point
with its nearest neighbour in another array. Used as a complement to package
'hutils' by sacrificing compilation or installation time for higher running
speeds. The name is a portmanteau of the author and 'Rcpp'.
