feather.plot {plotrix} | R Documentation |
Displays vectors along a line usually representing time or position.
feather.plot(r,theta,xpos,yref=0,use.arrows=TRUE, col.refline="lightgray",fp.type="s",main="",xlab="",ylab="", xlabels=NULL,...)
r |
radii of vectors |
theta |
direction of vectors in radians |
xpos |
where to start each vector along the reference line |
yref |
vertical position to place the reference line |
use.arrows |
whether to put arrow heads on the ends of the vectors |
col.refline |
the color of the reference line |
fp.type |
whether to use "standard" coordinates (begin at the right and move counterclockwise) or "meteorological" coordinates (begin at the top and move clockwise) when interpreting the values of theta |
main |
the title of the plot |
xlab |
the label for the reference line |
ylab |
the label for the vertical axis |
xlabels |
optional labels for the reference line |
... |
additional arguments passed to arrows or segments |
This function places vectors of length r and angle theta along a reference line that may represent time or position or some other value. The user is responsible for spacing the vectors so that they do not overlap if this is desired.
