New ggobi

Description

Creates a new ggobi instance

Usage

ggobi.default(data, args=character(0), mode=character(0), name = deparse(sys.call()[[2]]), ...)

Arguments

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
...

Details

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:

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.

Value

A ggobi object
