Description
Find unique values of a numeric vector
Usage
1
Arguments
x
Numeric vector
Details
A new algorithm for finding the unique values of a
numeric vector
It is dispatched to by unique and it calls
a c++ function that uses a hash
A little cheating is done since then hash algorithm does
not accept float keys. So the vector is converted to
character, the character uniqueing is done, then the
result is converted back to numeric.
Value
A numeric vector of the unique values www.jaredlander.com
