Finds values that occur exactly three times in a vector.
Usage
triplicate(x)
Arguments
x
A vector.
Details
Returns the triplicated values in the same order that they would be
returned in a call to orphan. This fundamentally
differs from triplicated, which returns
a logical vector that is TRUE when it runs into any but
the first or second occurrences of a value (and is therefore
dependent on the direction of testing of the vector).
