This function creates a new instance of GGobi with or without new data. Use
this function whenever you want to create a new GGobi indepdent of the
others—they will not share linked plots. If you want to add
another dataset to an existing ggobi, please see [<-.GGobi
There are currently three basic types of functions that you can use with rggobi:
Data getting and setting: see [.GGobi
, and [.GGobiData
"Automatic" brushing: see glyph_colour
,
glyph_size
, glyph_type
,
shadowed
, excluded
, and the associated
setter functions.
Edge modifcation: see edges
, edges<-
,
ggobi_longitudinal
You will generally spend most of your time working with
ggobdata
s, you retrieve using $.GGobiData
,
[.GGobiData
, or [[.GGobiData
.
Most of the time these will operate like normal R datasets while
pointing to the data in GGobi so that all changes are kept in sync.
If you need to force a ggobiDaataset to be an R data.frame
use
as.data.frame
.
