lines.rv: Add Connected (Random) Line Segments to a Plot
In jsta/rv: Simulation-Based Random Variable Objects

Description Usage Arguments Details Author(s) References Examples

Adds a sample of line segments randomly drawn from the joint distribution of (x,y).

1 2	## S3 method for class 'rv' lines(x, y, type = "l", ...)

`x, y`	coordinate vectors of points to join
`type`	character indicating the type of plotting, currently 'l' and 'p' are the only possibilities
`...`	further arguments passed to `points`

The size of the sample (number of segments drawn) is determined by rvpar(line.sample).

lines.rv is implemented as part of points.rv.

See points.rv for details of the parameters.
