R: Draws straight lines from point to point.

segments {compositions} | R Documentation

## Draws straight lines from point to point.

### Description

The function draws lines from a points x to a point y in the given geometry.

### Usage

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

### Arguments

`x0` | dataset of points (of the given type) to draw the line from
`y` | 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 functions add lines to the graphics generated with the corresponding plot functions.

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.
