CoCo {CoCo} | R Documentation |
The CoCo package with the interface functions to CoCo and CoCo for discrete data.
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.

# 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);
