plot3drmult: plot in 3D based on rgl

In compositions: Compositional Data Analysis

plot in 3D based on rgl

Description

3-dimensional plots, which can be rotated and zoomed in/out

Usage

## S3 method for class 'rmult'
plot3D(x,parts=1:3,...,
                 center=FALSE,scale=FALSE,add=FALSE,axes=!add,
                 cex=2,vlabs=colnames(x),size=cex,bbox=FALSE,col=1)

Arguments

x	an object to be plotted, e.g. a data frame or a data matrix
parts	the variables in the rmult object to be plotted
...	additional plotting parameters as described in rgl::material3d
center	logical, center the data? This might be necessary to stay within the openGL-arithmetic used in rgl.
scale	logical, scale the data? This might be necessary to stay within the openGL-arithmetic used in rgl.
add	logical, adding or new plot
bbox	logical, whether to add a bounding box
axes	logical, whether to plot a coordinate cross
cex	size of the plotting symbol (as expanding factor)
vlabs	labels for the variables
size	size of the plotting symbol, only size or cex should be used
col	the color used for dots, defaults to black.

Details

The function provides a generic interface for 3-dimensional plotting in analogy to the 2d-plotting interface of plot, using rgl package.

Value

the 3D plotting coordinates of the objects displayed, returned invisibly

Examples

x <- cbind(rnorm(10),rnorm(10),rnorm(10))
data(SimulatedAmounts)
if(requireNamespace("rgl", quietly = TRUE)) {
  plot3D(x)
  plot3D(rmult(sa.lognormals),cex=4,col=1:nrow(sa.lognormals))
} ## this function requires package 'rgl'
