Description of a pcanon object
Description
An object of class pcanon
that contains information derived from several
formulae
using designAnatomy
.
Value
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 byprojs.2canon
.Then there is a component for each further formulae; it contains the
p2canon.object
obtained by applyingprojs.2canon
to the structure for a formula and the already established joint decomposition of the structures for the previous formulae in theformulae
.The last component contains the the
list
of the projectors that give the combined canonical decomposition derived from all of theformulae
.
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.
