lines.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 |
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.
