add_matrix {matrixset}

Add matrices to the matrixset object

Description

Matrices to add must be of the same dimension and dimnames as .ms.

Either a named list of matrices can be supplied, or matrices can be specified separaely.

Usage

add_matrix(.ms, ...)

Arguments

.ms

A matrixset object.

...

A single list of matrices (must be a named list), or individual matrices, e.g. mat1 = m1, mat2 = m2, etc. NULL elements are accepted. This allows to create a placeholder that can be filled later on.

Value

A matrixset with updated matrices.

Examples

m1 <- matrix(1:60, 20, 3)
dimnames(m1) <- dimnames(student_results)
m2 <- matrix(101:160, 20, 3)
dimnames(m2) <- dimnames(student_results)

ms <- add_matrix(student_results, m1=m1, m2=m2)
ms2 <- add_matrix(student_results, list(m1=m1, m2=m2))
