assertive.matrices

A set of predicates and assertions for checking the properties of matrices. Most of the documentation is on the assertive page. End-users will usually want to use assertive directly.

Installation

To install the stable version, type:

install.packages("assertive.matrices")

To install the development version, you first need the devtools package.

install.packages("devtools")

Then you can install the assertive.matrices package using

library(devtools)
install_bitbucket("richierocks/assertive.matrices")

Predicates

is_identity_matrix, is_diagonal_matrix, is_symmetric_matrix, is_lower_triangular_matrix, is_upper_triangular_matrix, is_square_matrix and is_zero_matrix checks whether a variable is a matrix with suitable properties.

Assertions

Predicates all return a single logical value and have one corresponding assertion. For example, is_symmetric_matrix has assert_is_symmetric_matrix.
