validateMatrices {goalp}

Validates the input of a goal programming problem

Description

Validates the input of a goal programming problem

Usage

validateMatrices(
  A,
  b,
  m,
  w = NULL,
  p = NULL,
  setDefaults = FALSE,
  silent = FALSE
)

Arguments

A

Numeric matrix with the coefficients of the variables. One row per equation, one column per variable.

b

Numeric vector with the values on the right hand side of the goals.

m

Character vector with the relationship between the left and right-hand side of the goals. It can be any of =, ==, <=, >=.

w

Numeric matrix with the weights associated to the deviations from each goal. It should have as many rows as goals, and two columns: the first column corresponding to the weight of the positive deviation (excess), and the second column corresponding to the weight of the negative deviation (lack).

p

Numeric matrix indicating the priority of each deviation under a lexicographic approach. Lower numbers represent higher priority (e.g. from lower to higher priority: 1, 2, 3, ...). It must have as many rows as goals, and two columns.

setDefaults

Scalar logical. If TRUE, A, b, m, w, and p are filled in with default values as required.

silent

Logical. TRUE to prevent the function writing anything to the console (or the default output). Default is FALSE.
