Description

Test whether two matrices are identical by values and by dim names

Usage

identicalMatrix(x, y, epsilon = 1e-12)

Arguments

x	a matrix
y	another matrix
epsilon	accuracy threshold: absolute differences below this threshold is ignored

Value

Logical

Examples

set.seed(1887); x <- matrix(rnorm(1000), nrow=10, dimnames=list(LETTERS[1:10],NULL))
set.seed(1887); y <- matrix(rnorm(1000), nrow=10, dimnames=list(LETTERS[1:10],NULL))
set.seed(1887); z <- matrix(rnorm(1000), nrow=10, dimnames=list(letters[1:10],NULL))
stopifnot(identicalMatrix(x,y))
stopifnot(!identicalMatrix(x,z))
