pllimits: Determine Inner Plot Range

In regr0: Building regression models

Description

The inner plotting range is the range in which plotting functions of the regr0 package show unmodified coordinates. This function determines the range for one or more variables.

Usage

pllimits(pllim, data, limfac = 4, FUNC=robrange)

Arguments

pllim	either a logical: shall an inner plotting range be determined? – or a matrix with 2 rows and NCOL(data) rows, in which case the suitability will be checked.
data	vector or matrix or data.frame of data for which the inner plotting range is to be determined
limfac	scalar factor by which the range determined by FUNC is expanded
FUNC	function that determines the range of the data

Value

A matrix with 2 rows containing the minimum and the maximum of the inner plotting range. The columns correspond to those in data.
