overall_purity

A confusion matrix from <code><a rd-options="c2c" href="/link/get_conf_mat?package=c2c&version=0.1.0&to=c2c" data-mini-rdoc="c2c::get_conf_mat">get_conf_mat</a></code> or otherwise (ideally a matrix, although data frames will probably work)

conf_mat

Used to calculate overall cluster purity from a confusion matrix.

Compare two classifications or clustering solutions that may or may
not have the same number of classes, and that might have hard or soft
(fuzzy, probabilistic) membership. Calculate various metrics to assess how
the clusters compare to each other. The calculations are simple, but provide
a handy tool for users unfamiliar with matrix multiplication. This package
is not geared towards traditional accuracy assessment for classification/
mapping applications - the motivating use case is for comparing a
probabilistic clustering solution to a set of reference or existing class
labels that could have any number of classes (that is, without having to
degrade the probabilistic clustering to hard classes).
