The crosstalk package provides a way for different parts of an interactive display to communicate about datasets, using “shared data” objects. When selection or filtering is performed in one view, the result is mirrored in all other views.
This function allows vertices of RGL objects to be treated as shared data.
rglShared(id, key = NULL, group = NULL, deselectedFade = 0.1, deselectedColor = NULL, selectedColor = NULL, selectedIgnoreNone = TRUE, filteredFade = 0, filteredColor = NULL)
An existing RGL id.
Optional unique labels to apply to each vertex. If missing, numerical keys will be used.
Optional name of the shared group to which this data belongs. If missing, a random name will be generated.
Appearance of points that are not selected. See Details.
Appearance of points that are selected.
If no points are selected, should the points be shown
in their original colors (
TRUE), or in the
deselected colors (
Appearance of points that have been filtered out.
Some functions which normally work on dataframe-like datasets will accept shared data objects in their place.
If a selection is in progress, the alpha value for
unselected points is multiplied by
NULL, the color is left
as originally specified; if not, the point is changed to
the color given by
If no points have been selected, then by default points
are shown in their original colors. However, if
selectedIgnoreNone = FALSE, all points are displayed
as if unselected.
selectedColor argument is similarly used to
change the color (or not) of selected points, and
filteredColor are used for points that
have been filtered out of the display.
An object of class
"SharedData" (from the
optional crosstalk package) which
contains the x, y and z coordinates of the RGL object
with the given
