plot.fs: Feature signficance plot for 1- to 3-dimensional data

Description

Feature signficance plot for 1- to 3-dimensional data.

Usage

## S3 method for class 'fs':
plot(x, ..., xlab, ylab, zlab, xlim, ylim, zlim,
   add=FALSE, addData=FALSE, scaleData=FALSE, addDataNum=1000,
   addKDE=TRUE, jitterRug=TRUE,  
   addSignifGradRegion=FALSE, addSignifGradData=FALSE,
   addSignifCurvRegion=FALSE, addSignifCurvData=FALSE,
   addAxes3d=TRUE, densCol, dataCol="black", gradCol="green4",
   curvCol="blue", axisCol="black", bgCol="white",
   dataAlpha=0.1, gradDataAlpha=0.3, gradRegionAlpha=0.2,
   curvDataAlpha=0.3, curvRegionAlpha=0.3)

Arguments

x-, y-, z-axis limits

xlab, ylab, zlab

x-, y-, z-axis labels

scaleData

flag for scaling the data i.e. transforming to unit variance for each dimension

add

flag for adding to an existing plot

addData

flag for display of the data

addDataNum

maximum number of data points plotted in displays

addKDE

flag for display of kernel density estimates

jitterRug

flag for jittering of rug-plot for univariate data display

addSignifGradRegion,addSignifGradData

flag for display of significant gradient regions/data points

addSignifCurvRegion,addSignifCurvData

flag for display of significant curvature regions/data points

addAxes3d

flag for displaying axes in 3-d displays

densCol

colour of density estimate curve

dataCol

colour of data points

gradCol

colour of significant gradient regions/data points

curvCol

colour of significant curvature regions/data points

axisCol
