##### Draw boxes, axes and other text outside the data

These functions draw axes, boxes and text outside the range of the data. axes3d, box3d and title3d are the higher level functions; normally the others need not be called directly by users.

Keywords
dynamic
##### Usage
axes3d(edges = "bbox", labels = TRUE, tick = TRUE, nticks = 5,
box = FALSE, expand = 1.03, ...)
box3d(...)
title3d(main = NULL, sub = NULL, xlab = NULL, ylab = NULL,
zlab = NULL, line = NA, ...)
axis3d(edge, at = NULL, labels = TRUE, tick = TRUE, line = 0,
pos = NULL, nticks = 5, ...)
mtext3d(text, edge, line = 0, at = NULL, pos = NA, ...)
##### Arguments
edges

a code to describe which edge(s) of the box to use; see Details below

labels

whether to label the axes, or (for axis3d) the labels to use

tick

whether to use tick marks

nticks

suggested number of ticks

box

draw the full box if "bbox" axes are used

expand

how much to expand the box around the data

main

the main title for the plot

sub

the subtitle for the plot

xlab, ylab, zlab

the axis labels for the plot

line

the line'' of the plot margin to draw the label on

edge, pos

the position at which to draw the axis or text

text

the text to draw

at

the value of a coordinate at which to draw the axis

additional parameters which are passed to bbox3d or material3d

##### Details

The rectangular prism holding the 3D plot has 12 edges. They are identified using 3 character strings. The first character (x', y', or z') selects the direction of the axis. The next two characters are each -' or +', selecting the lower or upper end of one of the other coordinates. If only one or two characters are given, the remaining characters default to -'. For example edge = 'x+' draws an x-axis at the high level of y and the low level of z.

By default, axes3d uses the bbox3d function to draw the axes. The labels will move so that they do not obscure the data. Alternatively, a vector of arguments as described above may be used, in which case fixed axes are drawn using axis3d.

If pos is a numeric vector of length 3, edge determines the direction of the axis and the tick marks, and the values of the other two coordinates in pos determine the position. See the examples.

##### Value

These functions are called for their side effects. They return the object IDs of objects added to the scene.

Classic graphics functions axis, box, title, mtext, and rgl function bbox3d.

##### Examples
# NOT RUN {
open3d()
points3d(rnorm(10), rnorm(10), rnorm(10))

axes3d()

# and one in the middle (the NA will be ignored, a number would
# do as well)
axis3d('x', pos = c(NA, 0, 0))

title3d('main', 'sub', 'xlab', 'ylab', 'zlab')

rgl.bringtotop()

open3d()
points3d(rnorm(10), rnorm(10), rnorm(10))

# Use fixed axes

axes3d(c('x', 'y', 'z'))

# Put 4 x-axes on the plot
axes3d(c('x--', 'x-+', 'x+-', 'x++'))

axis3d('x', pos = c(NA, 0, 0))
title3d('main', 'sub', 'xlab', 'ylab', 'zlab')
# }
