Draw Labeled Vectors in 2D or 3D
Description
Graphics utility functions to draw vectors from an origin to a collection of points
(using arrows
in 2D or lines3d
in 3D)
with labels for each (using text
or texts3d
).
Usage
vectors(x, origin = c(0, 0), labels = rownames(x),
scale = 1,
col="blue",
lwd=1, cex=1,
length=.1, angle=13, pos=NULL,
...)
vectors3d(x, origin=c(0,0,0), labels=rownames(x),
scale=1,
col="blue",
lwd=1, cex=1,
...)
Arguments
x |
A two-column matrix or a three-column matrix containing the end points of the vectors |
origin |
Starting point(s) for the vectors |
labels |
Labels for the vectors |
scale |
A multiplier for the length of each vector |
col |
color(s) for the vectors. |
lwd |
line width(s) for the vectors. |
cex |
color(s) for the vectors. |
length |
For |
angle |
For |
pos |
For |
... |
other graphical parameters, such as |
Details
The graphical parameters col
, lty
and lwd
can be vectors of length greater than one and will be recycled if necessary
Value
