Variable Importance Plot

Description

Generates a dotchart of the importance of the most important interactions for an object of class logicFS or logicBagg.

Usage

## S3 method for class 'logicFS':
plot(x, topX = 15, cex = 0.9, pch = 16, col = 1, v0.col = "grey35",
   show.prop = FALSE, force.topX = FALSE, include0 = TRUE, coded = TRUE, ...)

## S3 method for class 'logicBagg':
plot(x, topX = 15, cex = 0.9, pch = 16, col = 1, v0.col = "grey35",
   show.prop = FALSE, force.topX = FALSE, include0 = TRUE, coded = TRUE, ...)

Arguments

x an object of either class logicFS or logicBagg.
topX integer specifying how many interactions should be shown. If topX is larger than the number of interactions contained in x all the interactions are shown. For further information, see force.topX.
cex a numeric value specifying the relative size of the text and symbols
pch specifies the used symbol. See ?par for details.
col the color of the text and the symbols. See ?par for how colors can be specified.
v0.col the color of the vertical line at x = 0. See ?par for how colors can be specified.
show.prop if TRUE the proportions of models that contain the interactions of interest are shown. If FALSE (default) the importances of the interactions are shown.
force.topX if TRUE exactly topX interactions are shown. If FALSE (default) all interactions up to the topXth most important one and all interactions having the same importance as the topXth most important one
include0 should x=0 be included regardless whether the importances of the shown interactions are much higher than 0?
coded should the coded variable names be displayed? Might be useful if the actual variable names are pretty long. The coded variable name of the yth variable is "Xy".
