rmultarithm {compositions} | R Documentation

## 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.
