Pixelmatrix function

Plot of a Pixel Matrix

Plots Data matrix as a pixel coulour image.

Pixelmatrix(Data, XNames, LowLim, HiLim,

YNames, main,FillNotFiniteWithHighestValue=FALSE)

Arguments

• Data: [1:n,1:d] Data cases in rows (n), variables in columns (d)
• LowLim: Optional: limits for the color axis
• HiLim: Optional: limits for the color axis
• XNames: Optional: Vector - names for the X-ticks, NULL: no ticks at all
• YNames: Optional: Vector - names for the Y-ticks, NULL: no ticks at all
• main: Optoinal: String - Title of the plot
• FillNotFiniteWithHighestValue: Optional: TRUE: fills not finite values with same color as the highest value
