plot3Drmult {compositions}

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
