rmult {compositions} | R Documentation |

## Simple treatment of real vectors

### Description

A class to collect real multivariate vectors.

### Usage

```
rmult(X,parts=1:NCOL(oneOrDataset(X)),orig=gsi.orig(X),
missingProjector=attr(X,"missingProjector"),
V = gsi.getV(X))
## S3 method for class 'rmult'
print(x,..., verbose=FALSE)
```

### Arguments

`X` |
vector or dataset of numbers considered as elements of a R-vector |

`parts` |
vector containing the indices xor names of the columns to be used |

`x` |
an rmult object |

`orig` |
the original untransformed dataset |

`missingProjector` |
the Projector on the observed subspace |

`V` |
the |

`...` |
further generic arguments passed to |

`verbose` |
logical, do you want to get all information about original data and transformation function (if any) with a |

### Details

The `rmult`

class is a simple convenience class to treat
data in the scale of real vectors just like data in the scale of real
numbers. A major aspect to take into account is that the internal arithmetic of R is
different for these vectors, e.g. `mean`

works as `colMeans`

in a data frame,
or matrix-vector operations are done row-wise.

### Value

a vector of class `"rmult"`

representing one vector
or a matrix of class `"rmult"`

, representing
multiple vectors by rows.
