check.dist: Check or fix a distance matrix.

In cultevo: Tools, Measures and Statistical Tests for Cultural Evolution

Description

Checks or fixes the given distance matrix specification and returns an equivalent, symmetric matrix object with 0s in the diagonal.

Usage

check.dist(x)

Arguments

x	an object (or list of objects) specifying a distance matrix

Details

If the argument is a matrix, check whether it is a valid specification of a distance matrix and return it, making it symmetric if it isn't already.

If the argument is a list, calls check.dist on every of its elements and returns a list of the results.

For all other object types, attempts to coerce the argument to a dist object and return the corresponding distance matrix (see above).

Value

a symmetric matrix object (or list of such objects) of the same dimension as x
