Creates a new ggobi instance
ggobi(data, args=character(0), mode=character(0), name = deparse(sys.call()[[2]]), ...)
data |
the name of a file containing the data, or a data frame or matrix containing the values |
args |
a character vector of command-line arguments |
mode |
data format GGobi should expect to read the data from, if reading from a file. |
name |
the name to use in GGobi for the dataset, if one is specified |
... |
Create a new instance of GGobi with or without new data. Use
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:
[.ggobi, and [.ggobiDataset
glyph_colour,
glyph_size, glyph_type,
shadowed, excluded, and the associated
setter functions.
edges, edges<-,
ggobi_longitudinal
You will generally spend most of your time working with
ggobDatasets, you retrieve using $.ggobiDataset,
[.ggobiDataset, or [[.ggobiDataset.
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.
