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
