general plotting function for data sets (matrix of row-elements), optionally associated to labels and a GMM. Labels influence the color and symbols of plotted data points. Gaussian envelopes of the components in the GMM are drawn. NB: data set and GMM arguments cannot be both NULL.

displayScatter(data = NULL, model = NULL, labels = NULL, datasizes = NULL, 
compcolors = NULL, complabels = NULL, compstrokes = "solid", space = 1:2, 
xlim = NULL, ylim = NULL, main = "", xlab = "", ylab = "", smooth = FALSE, 
alphacol = 0.8, alphanocol = 0.5, cex.lab = 1, lwd = 1)

`data`	matrix of row-elements. If NULL, the GMM is plotted alone.
`model`	GMM object.
`labels`	vector of numeric labels. May alternatively be present as a member of model, labels.
`datasizes`	vector of integer magnification factors for data symbols. If length=1, same coefficient applies to all points.
`compcolors`	vector of integer color indexes. These indexes are internally associated to one color among a set of appropriately chosen ones. If length=1, all GMM components are colored the same way. If length=k, each component is associated to its own color index. This k-length vector may contain NA values: associated components will be white-colored.
`complabels`	character vector containing text strings to be printed over Gaussian envelopes.
`compstrokes`	this character vector may be used to specify non default strokes for envelopes.
`space`	this function prints a 2D scatterplot. If data and model have higher dimensionality, this argument specifies the axes to be printed.
`xlim`	bounds for the first variable. If NULL, will be inferred from available data.
`ylim`	bounds for the second variable. If NULL, will be inferred from available data.
`main`	main label for the plotting window.
`xlab`	label for the x-axis.
`ylab`	label for the y-axis.
`smooth`	if TRUE, display the response to a kernel density function, instead of symbols for data elements.
`alphacol`	alpha blending parameter when a component is non-white colored.
`alphanocol`	alpha blending parameter when a component is white colored.
`cex.lab`	magnification factor for all text in the plotting window.
`lwd`	width of the stroke used for data symbols.
