segments: Draws straight lines from point to point.

In compositions: Compositional Data Analysis

Draws straight lines from point to point.

Description

The function draws lines from a points x0 to a point y1 in the given geometry.

Usage

          segments(x0,...)
          ## Default S3 method:
segments(x0,...)
          ## S3 method for class 'acomp'
segments(x0,y1,...,steps=30,aspanel=FALSE)
          ## S3 method for class 'rcomp'
segments(x0,y1,...,steps=30,aspanel=FALSE)
          ## S3 method for class 'aplus'
segments(x0,y1,...,steps=30,aspanel=FALSE)
          ## S3 method for class 'rplus'
segments(x0,y1,...,steps=30,aspanel=FALSE)
          ## S3 method for class 'rmult'
segments(x0,y1,...,steps=30,aspanel=FALSE)
          

Arguments

x0	dataset of points (of the given type) to draw the line from
y1	dataset of points (of the given type) to draw the line to
...	further graphical parameters
steps	the number of discretisation points to draw the segments, since the representation might not visually be a straight line
aspanel	Logical, indicates use as slave to do acutal drawing only.

Details

The default 'segments.default(x0,...)' redirects to 'segments' in package "graphics".

The other methods add lines to the graphics generated with the corresponding plot functions of "compositions"-classes.

Adding to multipaneled plots redraws the plot completely, and is only possible when the plot has been created with the plotting routines from this library.
