rgeneric-class: Organize data for the latent GMRF R interface for 'INLA'.

In INLAtools: Functionalities for the 'INLA' Package

Organize data for the latent GMRF R interface for INLA.

Description

A GMRF is defined from model parameters \theta that would parametrize a (sparse) precision matrix.

The elements of a GMR are:

• graph to define the non-zero precision matrix pattern. only the upper triangle including the diagonal is needed.

• Q vector where the

  • first element (N) is the size of the matrix,

  • second element (M) is the number of non-zero elements in the upper part (including) diagonal

  • the remaining (M) elements are the actual precision (upper triangle plus diagonal) elements whose order shall follow the graph definition.

• mu the mean vector,

• initial vector with

  • first element as the number of the parameters in the model

  • remaining elements should be the initials for the model parameters.

• log.norm.const log of the normalizing constant.

• log.prior log of the prior for the model parameters.

Usage

rgeneric(model, n, debug = FALSE, ...)

## Default S3 method:
rgeneric(model, n, debug = FALSE, ...)

## S3 method for class 'rgeneric'
rgeneric(model, ...)

## S3 method for class 'inla.rgeneric'
rgeneric(model, ...)

## S3 method for class 'rgeneric'
print(x, ...)

## S3 method for class 'rgeneric'
summary(object, ...)

## S3 method for class 'rgeneric'
plot(x, y, ...)

Arguments

model	an object used to define the model. See the 'rgeneric' vignette from the INLA package.
n	integer with the dimension of the model
debug	logical indicating debug state.
...	not used
x	a rgeneric object
object	a rgeneric object
y	not used

Value

rgeneric/ inla.rgeneric object.

Functions

• rgeneric(default): The rgeneric default method.

• rgeneric(rgeneric): Returns the model object unchanged.

• rgeneric(inla.rgeneric): Check and converts a regular inla.rgeneric object to rgeneric.

• print(rgeneric): Print the rgeneric object

• summary(rgeneric): A summary for a rgeneric object

• plot(rgeneric): A plot for a rgeneric object

Note

Recommended for prototyping, whereas cgeneric is recommended for production.
