R Data

Using the RData File option data can be loaded directly from a native R data file (usually with the exttt.RData). Such files may contain multiple datasets (usually in a compressed format) and will have been saved from R sometime previously (using the save function).

RData can be loaded by first identifying the file containing the data. The data will be loaded once the file is identified and we will be given an option to choose just one of the available data frames to be loaded as Rattle's dataset. We specify this through the Data Name combobox and then click Execute to make the dataset available within Rattle.
