axis3d

Drawing a 3D coordiante system to a plot, based on package rgl

Description

Adds a coordinate system to a 3D rgl graphic. In future releases, functionality to add tickmarks will be (hopefully) provided. Now, it is just a system of arrows giving the directions of the three axes.

Usage

axis3D(axis.origin=c(0,0,0),axis.scale=1,axis.col="gray",vlabs=c("x","y","z"),
       vlabs.col=axis.col,bbox=FALSE,axis.lwd=2,axis.len=mean(axis.scale)/10,
       axis.angle=30,orth=c(1,0.0001,0.000001),axes=TRUE,...)

Arguments

`axis.origin`	The location where to put the origin of the coordinate arrows typicall either 0, the minimum or the mean of the dataset
`axis.scale`	either a number or a 3D vector giving the length of the arrows for the axis in the coordiantes of the plot
`axis.col`	Color to plot the coordinate system
`vlabs`	The names of the axes, plotted at the end
`vlabs.col`	color for the axes labels
`bbox`	boolean, whether to plot a bounding box
`axis.lwd`	line width of the axes
`axis.angle`	angle of the arrow heads
`axis.len`	length of the arrow heads
`orth`	the orth argument of `arrows3D`
`axes`	a boolean, wether to plot the axes
`...`	these arguments are passed to arrows3D as `rgl::rgl.material` arguments

Details

The function is called to plot a coordiante system consisting of arrows into an rgl plot.

Examples

x <- cbind(rnorm(10),rnorm(10),rnorm(10))
if(requireNamespace("rgl", quietly = TRUE)) {
  plot3D(x)
  x0 <- x*0
  axis3D()
} ## this function requires package 'rgl'
