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.
