all.equal-methods: Matrix Package Methods for Function all.equal()

Description Methods Examples

Description

Methods for function all.equal() (from R package base) are defined for all Matrix classes.

Methods

target = "Matrix", current = "Matrix"

\

target = "ANY", current = "Matrix"

\

target = "Matrix", current = "ANY"

these three methods are simply using all.equal.numeric directly and work via as.vector().

There are more methods, notably also for "sparseVector"'s, see showMethods("all.equal").
