customDist

A metric, i.e. a function of two arguments that returns a numeric. Note
that a metric must be definite and symmetric, otherwise the results will be undefined.

metric

<code>TRUE</code> iff the diagonal of the distance matrix should be printed by
<code>print.dist</code>.

diag

<code>TRUE</code> iff the upper triangle of the distance matrix should be printed
by <code>print.dist</code>.

upper


This function computes and returns the distance matrix computed by using the given metric
to compute the distances between the rows of a data list or vector. Note that in contrast
to <code><a rd-options="" href="/link/dist?package=rgp&version=0.4-1" data-mini-rdoc="rgp::dist">dist</a></code>, <code>x</code> has to be a vector and the the distance <code>metric</code>
is an arbitrary function that must be symmetric and definite.


RGP is a simple modular Genetic Programming (GP) system build in
pure R. In addition to general GP tasks, the system supports Symbolic
Regression by GP through the familiar R model formula interface. GP
individuals are represented as R expressions, an (optional) type system
enables domain-specific function sets containing functions of diverse
domain- and range types. A basic set of genetic operators for variation
(mutation and crossover) and selection is provided.
