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.
You can get the iset object by calling the
iset function. An
iset object can be used in a way similar to data frames, so subsetting
and other operations work as expected. Subassignment is always done
"live", so changeing parts of the data will cause plots to be updated
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
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.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.
iset.rm removes the given iSet and all associated plots.
Note that this may cause the current set ID may change (even if some
other iSet is removed).
print.iset prints an iSet object.
