In corregp: Functions and Methods for Correspondence Regression

Description

Method to produce a 3D plot for a correspondence regression.

## S3 method for class 'corregp'
plot3d(x, axes = 1:3, y_btm = TRUE, y_ell = FALSE,
  x_ell = FALSE, ysub = NULL, xsub = NULL, hlim = NULL, vlim = NULL,
  dlim = NULL, asp = par3d("scale"), col_btm = "darkgrey",
  col_top = "red", cex_btm = par3d("cex"), cex_top = cex_btm,
  font_btm = par3d("font"), font_top = font_btm,
  fam_btm = par3d("family"), fam_top = fam_btm, col_ell = "black",
  lwd_ell = 1, lty_ell = "shade", opa_ell = 0.2, col_ori = "grey",
  lwd_ori = 1, main = NULL, sub = NULL, hlab = NULL, vlab = NULL,
  dlab = NULL, cl = 0.95, add_ori = TRUE, ...)

Arguments

x	The output of a call to corregp (i.e. an object of class "corregp").
axes	The axes to plot: a vector of three values. Defaults to the first three axes.
y_btm	Logical specifying whether the Y levels should be plotted first ("at the bottom") and then be overlaid by the X levels. Defaults to TRUE.
y_ell	Logical specifying whether the confidence ellipsoids of the Y levels should be plotted. Defaults to FALSE.
x_ell	Logical specifying whether the confidence ellipsoids of the X levels should be plotted. Defaults to FALSE.
ysub	Vector of indices to select a subset of the Y levels.
xsub	Vector of indices to select a subset of the X levels.
hlim	Vector of two values specifying the lower and upper limit between which to plot the horizontal axis.
vlim	Vector of two values specifying the lower and upper limit between which to plot the vertical axis.
dlim	Vector of two values specifying the lower and upper limit between which to plot the "depth" axis.
asp	The aspect ratio for the whole plot. See aspect3d.
col_btm	Color of the bottom levels: either numeric or see colors. Defaults to "darkgrey".
col_top	Color of the top levels: either numeric or see colors. Defaults to "red".
cex_btm	Character expansion factor of the bottom levels: a number to specify the size of the text labels.
cex_top	Character expansion factor of the top levels: a number to specify the size of the text labels.
font_btm	Font of the bottom levels: 1 for plain, 2 for bold, 3 for italic, and 4 for bold italic.
font_top	Font of the top levels: 1 for plain, 2 for bold, 3 for italic, and 4 for bold italic.
fam_btm	Font family of the bottom levels: can be "serif", "sans", "mono" or code"symbol".
fam_top	Font family of the top levels: can be "serif", "sans", "mono" or "symbol".
col_ell	Color of the confidence ellipsoids: either a number or see colors. Defaults to "black".
lwd_ell	Width of the confidence ellipsoids: a number to specify the line width.
lty_ell	Line type of the confidence ellipsoids: either "shade", "wire", or "dots". Defaults to "shade".
opa_ell	Opaqueness of the confidence ellipsoids: a number between 0 for fully transparent and 1 for fully opaque. Defaults to 0.2.
col_ori	Color of the lines through the origin: either a number or see colors. Defaults to "grey".
lwd_ori	Width of the lines through the origin: a number to specify the line width. Defaults to 1.
main	The main title of the plot.
sub	The subtitle of the plot.
hlab	The title of the horizontal axis.
vlab	The title of the vertical axis.
dlab	The title of the "depth" axis.
cl	The confidence level for the confidence ellipsoids. Defaults to 0.95.
add_ori	Logical specifying whether to add lines through the origin. Defaults to TRUE.
...	Further arguments passed to or from other methods.

Details

plot3d (of a corregp output) makes use of plot3d (and text3d and abclines3d) from the package rgl.

Value

A 3D plot window containing the output of a correspondence regression.

Examples

data(HairEye)
haireye.crg <- corregp(Eye ~ Hair * Sex, data = HairEye, b = 3000)
plot3d(haireye.crg, x_ell = TRUE, xsub = c("Hair", "Sex"))
