Plot LLE results

Description

Function for plotting LLE results either in static or in dynamic way.

Usage

plot_lle( Y, X, print = FALSE, col = 3, name = as.numeric(Sys.time()), 
                  angle = 60, inter = FALSE )

Arguments

`Y`	matrix object with calculated embedded data.
`X`	matrix object with original data.
`print`	a logical values indicating wheather to plot the graphical results to a file.
`col`	string or number dtermining the plotting colours.
`name`	(if `print==true`) filename.
`angle`	(if `inter==false`) angle between x- and y-axis in scatterplot3d. See documentation of scatterplot3d.
`inter`	a logical values indicating wheather to use interactive 3D-plots. See rgl.

Details

col determines the way that the points in the plot are coloured. Choosing a string name of a colour leads to a monocoloured plot. Choosing a number between leads to a colour gradient plot build up by N colours (taking only the rainbow colours into account). Choosing a numeric vector with length N leads to points coloured respecting to the values in the vector (for unique colours only values between 0 and 600 should be used).
If inter==false, two plots are generated in one window. The left plot is the plot of the original data. These will only be plotted if n \in \{1,2,3\}. The right plot shows the embedded data. These will only be plotted m \in \{1,2,3\}.
if inter==true, one interactive plot of the embedded data will be shown. This plot can be scrolled and zoomed. It requires OpenGL drivers.

Examples

data( lle_scurve_data )
	X <- lle_scurve_data
	Y <- lle( X, m=2, k=12 )$Y
	plot_lle( Y, X, FALSE, col="red", inter=TRUE )
