Data Mining Algorithms In R/Packages/optimsimplex/Get functions

Description
The functions extract the content to various elements of a simplex object:
 * optimsimplex.getall Get all the coordinates and the function values of all the vertices.
 * optimsimplex.getallfv Get all the function values of all the vertices.
 * optimsimplex.getallx Get all the coordinates of all the vertices.
 * optimsimplex.getfv Get the function value at a given index.
 * optimsimplex.getn Get the dimension of the space of the simplex.
 * optimsimplex.getnbve Get the number of vertices of the simplex.
 * optimsimplex.getve Get the vertex at a given index in the current simplex.
 * optimsimplex.getx Get the coordinates of the vertex at a given index in the current simplex.

Usage
optimsimplex.getall(this = NULL) optimsimplex.getallfv(this = NULL) optimsimplex.getallx(this = NULL) optimsimplex.getfv(this = NULL, ive = NULL) optimsimplex.getn(this = NULL) optimsimplex.getnbve(this = NULL) optimsimplex.getve(this = NULL, ive = NULL) optimsimplex.getx(this = NULL, ive = NULL)

Value
optimsimplex.getall Return a nbve x n+1 matrix, where n is the dimension of the space, nbve is the number of vertices and with the following content:
 * simplex[k,1] is the function value of the vertex k, with k = 1 to nbve,
 * simplex[k,2:(n+1)] is the coordinates of the vertex k, with k = 1 to nbve.

optimsimplex.getallfv Return a row vector of function values, which k^th element is the function value for the vertex k, with k = 1 to nbve. optimsimplex.getallx Return a nbve x n matrix of vertice coordinates; any given vertex is expected to be stored at row k, with k = 1 to nbve. optimsimplex.getfv Return a numeric scalar. optimsimplex.getn Return a numeric scalar. optimsimplex.getnbve Return a numeric scalar. optimsimplex.getve Return a list with a ’type’ attribute set to ’T_VERTEX’ and with the following elements:
 * n The dimension of the space of the simplex.
 * x The coordinates of the vertex at index ive.
 * fv The value of the function at index ive.

optimsimplex.getx Return a row vector, representing the coordinates of the vertex at index ive.
