iset.list: iSet management functions.

Description

These functions are used to manage iSets. An iSets groups all iPlots which use the same data as a basis. All iPlots belonging to an iSet are linked, that is selecting cases in one iPlot cause the same cases to be highlighted in all other iPlots based on the same iSet. The linking is done on case-level, therefore the variables should have the same number of cases. There is always exactly one current iSet. An initial iSet called "default" is created when the iplots library is loaded. All new iPlots are created using the current iSet. The set of functions described here allow the manipulation of iSets. Note that changing the iSet also has an effect on iplot.list and iobj.list since iPlots are linked to their iSets. iset.new creates a new iSet and makes it current iset.list returns all iSets iset.cur returns the ID of the current iSet iset.next and iset.prev return the ID of the next resp. previous iSet in the list relative to the iSet specified by the argument. iset.set makes the iSet with the specified ID current.

Usage

iset.new(name=NULL)
iset.list()
iset.cur()
iset.next(which=iset.cur())
iset.prev(which=iset.cur())
iset.set(which=iset.next())

Arguments

name

Name of the new iSet. If no name is specified, an automatic name of the form "data.X" is created where "X" is an integer. The name can be used instead on an ID in many cases.

which

An integer specifying an iSet ID or a string specifying a name of the iSet.
