CoCo {CoCo}R Documentation

The CoCo package

Description

The CoCo package with the interface functions to CoCo and CoCo for discrete data.

Note

The function dG is an "alias" for dg, but with loading the packages "CoCoGraph" and "dynamicGraph". These packages with dg for CoCo-objects are not loaded when loading the package "CoCo" to make the loading of "CoCo" faster.

For help on dg use help(dg, package = "dynamicGraph").

Please quit by quitCoCo to remove temporary files.

Examples

# Attach data, here table of counts:
data(Reinis);

# Create a CoCo-object:
CoCoObject <- makeCoCo();

# Enter the table of counts into the CoCo-object:
enterTable(Reinis, object = CoCoObject);

# Enter the saturated model into the CoCo-object, and return a model object:
fullModel <- makeModel(enterModel("*", object = CoCoObject));

# Display a graph of the model:
fullGraph <- dG(fullModel, title = "Full", returnLink = TRUE);

# Do a backward elimination of edges:
backward(recursive = TRUE, headlong = TRUE, coherent = TRUE,
         follow = TRUE, object = CoCoObject);

# Display the result of the backward elimination:
lastModel <- makeModel("last", object = CoCoObject);
backwardGraph <- dG(lastModel, title = "Last", 
                    dynamicGraph = fullGraph, slave = TRUE);

# Do the EH-procedure:
eh(object = CoCoObject);

# Terminate the CoCo-object with disposing temporary files:
endCoCo(object = CoCoObject);
