## Assertions to Check Properties of Matrices

A set of predicates and assertions for checking the properties of matrices. This is mainly for use by other package developers who want to include run-time testing features in their own packages. End-users will usually want to use assertive directly.

# 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.
