Matrix operations based on matching dimensions

Matrix operations based on matching dimensions

matrix_op(m1, m2, op = `+`)

Arguments

m1, m2

matrices with dimnames

op

the operation to be performed

Examples

nms1 <- letters[1:4]
mat1 <- matrix(1:8, nrow=4, ncol=4, dimnames=list(nms1, nms1))

nms2 <- letters[2:3]
mat2 <- matrix(11:18, nrow=2, ncol=4, dimnames=list(nms2, nms1))

matrix_op(mat1, mat2)
#>    a  b  c  d
#> a  1  5  1  5
#> b 13 19 17 23
#> c 15 21 19 25
#> d  4  8  4  8
matrix_op(mat1, mat2, `*`)
#>    a  b  c   d
#> a  1  5  1   5
#> b 22 78 30 102
#> c 36 98 48 126
#> d  4  8  4   8
