checksAn 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.
