Description Usage Arguments Details Value Author(s)

View source: R/simplex.R

Description

These functions support the S3 classes 'simplex' and 'vertex'. They are intended to either create objects of these classes or check if an object is of these classes

  ## S3 method for class 'vertex'
is(x)

Arguments

verbose

The verbose option, controlling the amount of messages

x

The coordinates of the vertices, with size nbve x n in a simplex object or 1 x n in a vertex.

n

The dimension of the space.

fv

The values of the function at given vertices. It is a column matrix of length nbve in a simplex or a single value in a vertex.

nbve

The number of vertices in a simplex.

...

optional arguments to 'print' or 'plot' methods.

Details

A simplex of size n x nbve is essentially a collection of vertex of size n.

Value

simplex returns a list with the following elements: verbose, x, n, fv, and nbve. vertex returns a list with the following elements: x, n, and fv.
