zoom star chart for symbolic data

Description

plot in a form of zoom star chart for symbolic object described by interval-valued, multivalued and modal variables

Usage

zoomStar(table.Symbolic, j, variableSelection=NULL, offset=0.2, 
firstTick=0.2, labelCex=.8, labelOffset=.7, tickLength=.3, histWidth=0.04, 
histHeight=2, rotateLabels=TRUE, variableCex=NULL)

Arguments

table.Symbolic	symbolic data table
j	symbolic object number in symbolic data table used to create the chart
variableSelection	numbers of symbolic variables describing symbolic object used to create the chart, if NULL all variables are used
offset	relational offset of chart (margin size)
firstTick	place of first tick (relational to lenght of axis)
labelCex	labels cex parameter of labels
labelOffset	relational offset of labels
tickLength	relational length of single tick of axis
histWidth	histogram (for modal variables) relational width
histHeight	histogram (for modal variables) relational heigth
rotateLabels	if TRUE labels are rotated due to rotation of axes
variableCex	cex parameter of names of variables

Value

zoom star chart for selected symbolic object in which each axis represents a symbolic variable. Depending on the type of symbolic variable their implementations are presented as:

a) rectangle - interval range of interval-valued variable),

b) circles - categories of multinominal (or multinominal with weights) variable from among coloured circles means categories of the variable observed for the selected symbolic object

bar chart - additional chart for multinominal with weights variable in which each bar represents a weight (percentage share) of a category of the variable
