getSelectedIndices.ggobi {Rggobi} | R Documentation |
The user can select different records in a ggobi dataset
using the brushing region.
These functions provide two ways to query
the set of selected observations.
One (getSelectedIndices.ggobi
) returns the indices of the selected records.
The other is a simple transformation of this information
which indicates, via a logical vector, for each record
whether it is currently selected.
getSelectedIndices.ggobi(.data = 1, .gobi=getDefaultGGobi()) isObservationSelected.ggobi(.data = 1, .gobi=getDefaultGGobi())
.data |
the dataset whose selected status is to be queried.
This can be any identifier for a dataset, specifically a name, index
or an object of class ggobiDataset . |
.gobi |
an identifier for the ggobi instance in which the dataset
to be queried resides. This is either an index or an object of class
ggobi . This is not necessary if the .data argument
is supplied in the form of an object of class ggobiDataset . |
getSelectedIndices.ggobi
returns
an integer vector containing the indices of the records
in the specified dataset that are currently selected.
isObservationSelected.ggobi
returns a logical vector the length of which is the number
of records in the specified dataset and in which
each element indicates whether the corresponding record
is currently selected.
