Plot3D: 3D plot of points

In DataVisualizations: Visualizations of High-Dimensional Data

3D plot of points

Description

A wrapper for Data with systematic clustering colors for either a 2D (x,y) or 3D (x,y,z) plot combined with a classification

Usage

Plot3D(Data,Cls,UniqueColors,

size=2,na.rm=FALSE,Plotter3D="rgl",...)

Arguments

Data	[1:n,1:d] matrix with either d=2 or d=3, if d>3 only the first 3 dimensions are taken
Cls	[1:n] numeric vector of the classification of data with k classes
UniqueColors	[1:k] character vector of colors, if not given DataVisualizations::DefaultColorSequence is used
size	size of points, for plotly additional a vector [1:n] of a mapping of sizes to Cls has to be given in the (...) argument with sizes=
na.rm	if na.rm=TRUE, then missing values are removed
Plotter3D	in case of 3 dimensions, choose either "plotly" or "rgl", if one of this packages is not given, the other one is selected as a fallback method
...	further arguments to be processed by plot3d or geom_point or plot_ly of type "scatter3d"

Details

For geom_point only size and na.rm is available as further arguments.

Note

Uses either geom_point for 2D or plot3d for 3D or plot_ly

#Spin3D similar output

#Projected Points with Classification

# Classification
