CheckInput {Delta}

Main Check Input function

Description

This function perform multiple tasks. First of all, check the parameters specified by the user. Also asign default values to some parameters not defined by the user. Finally it generates error messages and halt the execution in case it is needed.

Usage

CheckInput(datatable, fixedrows = FALSE, gstandard = "No",
  maxits = 1000, tol = 1e-12, dplaces = 4, showall = FALSE)

Arguments

datatable

Matrix. Expected to be square matrix with at least 2 rows (columns), non negative values and at least an element different of zero.

fixedrows

Boolean. Indicate if sample rows are fixed beforehand. Default is TRUE.

gstandard

Text. Indicate if there are a Gold Standard by Rows or columns. Only first letter matter without Case sensitivity. Options are: "N" for None, "R" for in Rows and "C" for in Columns. Default is "N".

maxits

Whole number. Indicate the maximum number of iterations of the numeric method to calculate B. Expected to be 100 <= maxits <= 5000. Default is 1000.

tol

Double number. Indicate the precision of the numeric method to calculate B. Expected to be 1e-6 <= tol <= 1e-15.Default is 1e-12.

dplaces

Whole number. Decimal placed to be shown in the result. Expected to be 1 <= dplaces <0 6. Default 4.

showall

Boolean. Indicate if all output should be shown. If TRUE also shown hidden results. If FALSE shown only main output. By default is FALSE.

Examples

CheckInput(matrix(c(1,2,3,4),2,2),fixedrows=FALSE,gstandard="No",maxits=100,tol=1e-12,dplaces=4)
