Description

Plot density of two-dimensional data.

Usage

plotDensity(Data, Cls, CurrGauss, Colors,
GridDensity,Means, Covariances,Weights,
MainAxesAngle,XKernel, YKernel, Shapes, ShapeText,
AxNames = c("X1", "X2"),ShowAxis = FALSE, ShowEllipsoids = TRUE,
ShowScatter = FALSE,ShowGaussNr = FALSE, Source = "D")

Arguments

`Data`	[1:n, 1:2] Numeric matrix with n observations and 2 features.
`Cls`	[1:n] Numerical vector of size n containing the classes of each observation.
`CurrGauss`	Integer number indicating the currently highlighted gaussian component.
`Colors`	[1:l] Character vector with l color names or more.
`GridDensity`	[1:x, 1:x] Numeric matrix with PDF for a GMM with one or more Gaussians on a Grid defined by the vectors XKernel and YKernel.
`Means`	List with l [1:2] numerical vector defining the means of the l GMM components.
`Covariances`	List with l [1:2, 1:2] numerical matrices defining the covariance matrices of the l GMM components.
`Weights`	[1:l] Numerical vector with weights for each GMM component.
`MainAxesAngle`	List of numeric vectors with 1st and 2nd main axes of a 2D ellipsoid and the respective angles measured to the first unit vector c(0,1).
`XKernel`	[1:x] Numeric vector defining domain of x axis.
`YKernel`	[1:x] Numeric vector defining domain of y axis.
`Shapes`	List of List with 4 attributes (type, fillcolor, opacity, path) for a shape for plotting. Here it is used for plotting an ellipsoid.
`ShapeText`	[1:l, 1:3] Numeric matrix with l means and two entries for the two-dimensional coordinates and one entry for the number of the Gaussian component.
`AxNames`	[1:2] Character vector with ax names for plot description.
`ShowAxis`	Boolean indicating to show models axis or not.
`ShowEllipsoids`	Boolean indicating to show models ellipsoids or not.
`ShowScatter`	Boolean indicating if data scatter is shown or not.
`ShowGaussNr`	Boolean indicating to enumerate model components.
`Source`	Character indicating plot source (Default = "D"). Important attribute for plotly in shiny in order to keep control of specific panels.
