Create matrices from vector input

These functions are simple utilities for creating diagonal, block or correlation matrices.

bmat(..., correlation = FALSE, digits = -1)

cmat(..., digits = -1)

dmat(...)

Arguments

...

matrix data.

correlation

logical; if TRUE, off-diagonal elements are assumed to be correlations and converted to covariances.

digits

if greater than zero, matrix is passed to signif() (along with digits) prior to returning.

Value

A matrix.

Details

bmat() makes a block matrix. cmat() makes a correlation matrix. dmat() makes a diagonal matrix.
