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". In addition the
metric can be any function that takes two vectors as arguments and
returns their distance. All predefined functions will return NA or NaN
when one of the compared vectors contains NAs.
