R: Prints Logic Regression Formula

print.logregtree {LogicReg} | R Documentation

## Prints Logic Regression Formula

### Description

Prints formulas for objects fitted by `logreg`.

### Usage

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

### 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

### Value

A text representation of the tree will be printed.
