rmultarithm {compositions}

vectorial arithmetic for datasets in a classical vector scale

Description

vector space operations computed for multiple vectors in parallel

Usage

## Methods for class "rmult"
## x+y
## x-y
## -x
## x*r
## r*x
## x/r

Arguments

x

an rmult vector or dataset of vectors

y

an rmult vector or dataset of vectors

r

a numeric vector of size 1 or nrow(x)

Details

The operators try to mimic the parallel operation of R on vectors of real numbers on vectors of vectors represented as matrices containing the vectors as rows.

Value

an object of class "rmult" containing the result of the corresponding operation on the vectors.
