create_enrichwith_skeleton: Create a enrichwith skeleton

In enrichwith: Methods to Enrich R Objects with Extra Components

Description

Create an enrichwith skeleton file for the structured implementation of methods to compute new components for objects of a specific class

Usage

create_enrichwith_skeleton(class, option, description, component, path,
  filename = paste0(class, "_options.R"), attempt_rename = TRUE)

Arguments

class	the class of the objects to be enriched
option	a character vector with components the enrichment options
description	a character vector of length length(options) with components the description of the enrichment options
component	a list of as many character vectors as length(option), specifying the names of the components that each option will add to the object after enrichment
path	the path where the skeleton file will be created
filename	the name of the skeleton file
attempt_rename	attempt to rename syntactically incorrect component names? Default is TRUE

Value

A file with the necessary functions to use enrichwith infrastructure. The skeleton consists of the following functions

• One compute_component.class function per component name from unique(unlist(component)). The function takes as input the object to be enriched and returns as output the component to be added to the object.

• The get_enrichment_options.class function, that takes as input the object to be enriched and an enrichment option, and returns the names of the components that will be appended to the object for this option. This function can also be used to list the available options and print their description.

• The enrich.class function

      description = c("various likelihood-based quantities
        (gradient of the log-likelihood, expected and observed
        information matrix and first term in the expansion of
