3D Radial Visualization function

Description

3D Radial Visualization function

Usage

radialvis3d(
  data,
  domrp = T,
  doGtrans = F,
  sqrt_scale = F,
  cl = NULL,
  color = NULL,
  pch = 16,
  colorblind = FALSE,
  axes = FALSE,
  point.cex = 1,
  with.coord.labels = T,
  coord.labels = NULL,
  coord.font = 2,
  coord.cex = 1.1,
  with.class.labels = T,
  class.labels = levels(factor(cl)),
  class.labels.locations = NULL,
  opt.anchor.order = FALSE,
  alpha = 0.02,
  lwd = 1,
  axes.col = "black",
  ret.trans = FALSE,
  ...
)

Arguments

data	The dataset to visualize. Each row is an observation.
domrp	Logical. If true, MRP is applied to the origianl dataset. The default number of PCs used is npc = 4.
doGtrans	Logical. If true, Gtrans is applied to the origianl dataset. @seealso Gtrans.
sqrt_scale	Logical. If true, the distance of the points to be visualization will be augmented to squre root of the orginal distance to make points further away from the origin.
cl	The class identification for each observation. The length of cl should be the same as the number of rows of data. If specified, different classes would be visualized with different colors.
color	The colors for different classes. If not specified, rainbow is used.
pch	The point character to be used. It is an integer of a vector of integers of the same length of the nrow of the dataset. See points for a complete list of characters.
colorblind	Logical.The colors for different classes.If true, poits are colorblind friendly.If false, rainbow is used.
axes	Logical.If true, Cartesian axes would be plotted.
point.cex	The size of the data point in RadViz3D. The default value is 1.
with.coord.labels	Logical. If true, labels of coordinates will be added to the visualization.
coord.labels	The labels for components of the dataset. When domrp = TRUE, the coord.labels will be changed to "Xi" representing the the ith direction obtained with MRP.
coord.font	The font for labels of components.
coord.cex	The size of the labels of components.
with.class.labels	Logical. If true, class labels will be added to the visualization.
class.labels	The labels for different classes in the dataset.
class.labels.locations	Locations to put labels for each class. If not specified, an optimal location for each class would be calculated.
opt.anchor.order	Logical. If true, the optimal order of anchor points corresponding to the components would be calculated. This is a very time consuming procedure. Not recommended if the number of components is larger then 6.
alpha	The alpha value that controls the transparency of the sphere in 3d visulization
lwd	The line width in the visualization
axes.col	Colors of the axes, if needed to be displayed
ret.trans	Logical parameter, returns the Radviz3D transformation if TRUE
...	Some other parameters from mrp and Gtrans and rgl functions.

Value

A list with the elements

mrp.res

The result of MRP is the argument domrp = TRUE. See also mrp.
