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.

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.

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")`

`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.

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

has `assert_is_symmetric_matrix`

.
