Projects

A project is a packaging of a dataset, variable selections, explorations, and models built from the data. Rattle allows projects to be saved for later resumption of the work or for sharing the data mining project with other users.

A project is typically saved to a file with the exttt.rattle extension. In reality it is a standard binary exttt.RData file used by R to store objects in binary form. Any R system can load such a file and hence have access to these objects, even without running Rattle.

Loading a exttt.rattle file into Rattle (using the Open button) will load that project into Rattle, restoring the data, models, and other displayed information relating to the project, including the Log and summary information. We can then resume our data mining from that point.

From a file system point of view, we can rename the files (as well as the filename extension, though that is not recommended) without impacting the project file itself--that is, the file name has no formal bearing on the contents, so use it to be descriptive. It is best to avoid spaces and unusual characters in the filenames.

Projects are opened and saved using the appropriate buttons on the toolbar or from the Project menu.
