rmultarithm: 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

Value

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

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.
