Matrix of random values, possibly with standardization by row or column

Description

This function creates a matrix populated by random uniform values and (at the user's discretion), standardizes the rows, columns, or entire matrix so values sum to 1.

Usage

runifMatrix(nrow, ncol, min = 0, max = 1, stand = NULL)

Arguments

nrow, ncol	Number of rows and columns.
min, max	Minimum and maximum value of values.
stand	Any of: NULL (default): No standardization. 'rows': Standardize so rows sum to 1. 'columns': Standardize so columns sum to 1. 'matrix': Standardize so all values sum to 1. Partial matching is used and case is ignored.

Value

A numeric matrix.

Examples

rows <- 4
cols <- 3

runifMatrix(rows, cols)

standByRows <- runifMatrix(rows, cols, stand = 'r')
standByRows
rowSums(standByRows)

standByCols <- runifMatrix(rows, cols, stand = 'c')
standByCols
colSums(standByCols)

standByMe <- runifMatrix(rows, cols, stand = 'm')
standByMe
sum(standByMe) # whenever you're in trouble
