Saves data to a file.

Signals

Inputs:
  • Data

    Attribute-valued data set.

Outputs:
  • (None)

Description

Save widget considers a data set provided on the input channel and saves it to a data file with the specified name. The widget remembers a history of the most recent file names. It can save into tab-delimited and comma-separated files, as well as the C4.5’s format and Weka’s .arrf files.

By design, the widget does not save the data every time it receives a new signal on the input as this would constantly (and, mostly, inadvertently) overwrite the file. Instead, the data is saved only after a new file name is set or the user pushes Save button.
