rmat: Simple matrix wrapper for gnerating random numbers.

In hstojic/hfunk: Useful R functions

Description

A shortcut for creating a matrix with randomly drawn numbers from arbitrary distribution available in R.

Usage

rmat(distribution, nrow, ncol, byrow = TRUE, ...)

Arguments

distribution	A distribution available in R that should generate the numbers for filling out the matrix, e.g. rnorm or coderunif.
nrow	A scalar indicating the desired number of rows.
ncol	A scalar indicating the desired number of columns.
byrow	A logical value, if TRUE (the default) the matrix is filled by rows, otherwise the matrix is filled by columns.
...	Additional arguments to be passed to or from methods.

Value

A matrix with nrow rows and ncol columns, filled with numbers generated from distribution.

See Also

matrix, rnorm, runif etc.

Examples

# create a 2 by 2 matrix with numbers randomly drawn from uniform distribution
rmat(runif, 2, 2)

# same, but now we pass on additional arguments to runif 
rmat(runif, 2, 2, min=10, max=20)
