summary.pdMat

Summarize a pdMat Object

Description

Attributes structName and noCorrelation, with the values of the corresponding arguments to the method function, are appended to object and its class is changed to summary.pdMat.

Usage

## S3 method for class 'pdMat'
summary(object, structName, noCorrelation, ...)

Arguments

`object`	an object inheriting from class `"pdMat"`, representing a positive definite matrix.
`structName`	an optional character string with a description of the `pdMat` class. Default depends on the method function: `"Blocked"` for `pdBlocked`, `"Compound Symmetry"` for `pdCompSymm`, `"Diagonal"` for `pdDiag`, `"Multiple of an Identity"` for `pdIdent`, `"General Positive-Definite, Natural Parametrization"` for `pdNatural`, `"General Positive-Definite"` for `pdSymm`, and `data.class(object)` for `pdMat`.
`noCorrelation`	an optional logical value indicating whether correlations are to be printed in `print.summary.pdMat`. Default depends on the method function: `FALSE` for `pdDiag` and `pdIdent`, and `TRUE` for all other classes.
`...`	some methods for this generic require additional arguments. None are used in this method.

Value

an object similar to object, with additional attributes structName and noCorrelation, inheriting from class summary.pdMat.
