setlimits1D: 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)

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.

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
