LogicReg (version 1.6.6)

print.logregtree: Prints Logic Regression Formula

Description

Prints formulas for objects fitted by logreg.

Usage

# S3 method for logregtree
print(x, nms, notnms, pstyle, ...)

Value

A text representation of the tree will be printed.

Arguments

x

object of class logregtree, typically a part of an object of class logreg, which is the result of the function logreg, or a matrix with five columns (see logregtree).

nms

names of variables. If nms is provided variable names will be printed, otherwise indices will be used.

notnms

names of complements of the variables. If notnms is not provided ``not'' will be added before the variable names.

pstyle

parenthesis style. If pstyle = 1 (the default) rules are more compact than if pstyle = 2.

...

other options are ignored
