| lines.rv {rv} | R Documentation |
Adds a sample of line segments randomly drawn from the joint distribution of
(x,y).
## 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.
