pcanon.object {dae} | R Documentation |

An object of class `pcanon`

that contains information derived from several
`formulae`

using `designAnatomy`

.

A `list`

of class `pcanon`

that has four components: (i) `Q`

,
(ii) `terms`

, (iii) `sources`

, (iv) `marginality`

, and (v) `aliasing`

.
Each component is a `list`

with as many components as there
are formulae in the `formulae`

`list`

supplied to `designAnatomy`

.

The `Q`

`list`

is made up of the following components:

The first component is the joint decomposition of two structures derived from the first two formulae, being the

`p2canon.object`

produced by`projs.2canon`

.Then there is a component for each further formulae; it contains the

`p2canon.object`

obtained by applying`projs.2canon`

to the structure for a formula and the already established joint decomposition of the structures for the previous formulae in the`formulae`

.The last component contains the the

`list`

of the projectors that give the combined canonical decomposition derived from all of the`formulae`

.

The `terms`

, `sources`

, `marginalty`

and `aliasing`

`list`

s have a component for each `formula`

in the
`formulae`

argument to `designAnatomy`

,
Each component of the `terms`

and `sources`

`list`

s has
a `character`

vector containing the terms or sources derived from its
`formula`

. For the `marginality`

component, each component is the
marginality `matrix`

for the `terms`

derived from its
`formula`

. For the `aliasing`

component, each component is the
aliasing `data.frame`

for the `source`

derived from its
`formula`

. The components of these four `list`

s are
produced by `pstructure.formula`

and are copied from the
`pstructure.object`

for the `formula`

.
The names of the components of these four lists will be the names of the components
in the `formulae`

list.

The object has the attribute `labels`

, which is set to `"terms"`

or
`"sources"`

according to which of these were used to label the projectors
when the object was created.
