setlimits1D: Computes limits for 1D and 2D displays.

In adegraphics: An S4 Lattice-Based Package for the Representation of Multivariate Data

Computes limits for 1D and 2D displays.

Description

Computes limits for 1D and 2D displays adding 10% of margins around the extreme values.

Usage

setlimits1D(mini, maxi, origin, includeOr)
setlimits2D(minX, maxX, minY, maxY, origin = c(0, 0), aspect.ratio = "iso", includeOr)

Arguments

mini	the smallest value of a unidimensional dataset
maxi	the largest value of a unidimensional dataset
minX	the smallest value of the first dimension of a bidimensional dataset
maxX	the largest value of the first dimension of a bidimensional dataset
minY	the smallest value of the second dimension of a bidimensional dataset
maxY	the largest value of the second dimension of a bidimensional dataset
origin	a value (in setlimits1D) or a two-length vector (in setlimits2D) indicating origin coordinate(s)
aspect.ratio	a character string to control physical aspect ratio of the graphic. iso for isometric scales, fill for drawing as big as possible or xy for banking rule
includeOr	a boolean value indicating whether the origin is included in the graphics window

Value

setlimits1D returns a two-length vector containing the limits of the graphics window on one axis.
setlimits2D returns a two-length list where the first element, named xlim, contains a two-length vector containing the limits of the graphics window on the first axis and the second, named ylim, contains the limits on the second axis.
