rdist 0.0.1 2017-03-05

An R package to calculate distances. This provide a common framework to calculate distances.
There are three main functions:

• rdist computes the pairwise distances between observations in one matrix and returns a dist object,
• pdist computes the pairwise distances between observations in one matrix and returns a matrix, and
• cdist computes the distances between observations in two matrices and returns a matrix.

All functions have an argument metric that can be used to specify the distance function. Available metrics are "euclidean", "minkowski", "manhattan", "maximum", "canberra", "angular", "correlation", "absolute_correlation", "hamming", and "jaccard". All functions will return NA or NaN when one of the compared vectors contains NAs.
