ggobi-default-20: New ggobi
In rggobi: Interface Between R and 'GGobi'

Description Usage Arguments Details Value Author(s) Examples

Creates a new ggobi instance

1 2	## Default S3 method: 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
`...`	ignored

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 ggobdatas, 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.
