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 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
lists have a component for each formula in the
formulae argument to designAnatomy,
Each component of the terms and sources lists 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 lists 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.
