37<p>Takes a data set provided at the input channel and saves it to a
38data file with the specified name. The widget remembers a history of the most recent file names.
39It can save into tab-delimited and comma-separated files, as well as the
40C4.5's format and Weka's .arrf files.</p>
41
42<p>The widget does not save the data every time it receives a new signal on
43the input as this would constantly (and, mostly, inadvertently) overwrite
44the file. Instead the data is saved after a new file name is set or the
45user pushes <span class="option">Save current data</span>.</p>

50<p>The schema below can be used to train the naive Bayesian classifier on the data loaded
51from a file, use the classifier on data from another file and save the misclassified examples
52(or the correctly classified, depending on what we select in the Confusion Matrix) into a file.</p>
