R Dataset Option

Rattle can use a dataset that is already loaded into R (although it will take a copy of it, with memory implications). Only data frames are currently supported, and Rattle will list for you the names of all of the available data frames.

The data frames need to be constructed in the same R session that is running Rattle (i.e., the same R Console in which you lo the Rattle package). This provides much more flexibility in loading data into Rattle, than is provided directly through the actual Rattle interface. For example, you may want to load data from an SQLite database directly, and have this available in Rattle.
