scores | R Documentation |

These functions extract score and loading matrices from fitted `mvr`

models.

```
loadings(object, ...)
## Default S3 method:
loadings(object, ...)
scores(object, ...)
## Default S3 method:
scores(object, ...)
Yscores(object)
loading.weights(object)
Yloadings(object)
```

`object` |
a fitted model to extract from. |

`...` |
extra arguments, currently not used. |

All functions extract the indicated matrix from the fitted model, and will work with any object having a suitably named component.

The default `scores`

and `loadings`

methods also handle
`prcomp`

objects (their scores and loadings components are called
`x`

and `rotation`

, resp.), and add an attribute `"explvar"`

with the variance explained by each component, if this is available. (See
`explvar`

for details.)

A matrix with scores or loadings.

There is a `loadings`

function in package stats. It simply
returns any element named `"loadings"`

. See
`loadings`

for details. The function can be accessed as
`stats::loadings(...)`

.
