writeGroupDataset

public void writeGroupDataset(CSV csv,
                              java.lang.String filename)

This methods will create a text file and output the dataset to that file in a CSV (Comma Separated Value) format. A CSV file can be read by popular spreadsheet and word processing programs. Some localization for different operating systems and locales can be handled by the modifying the default csv (CSV) object. The file can be organized so that the columns represent groups and the rows represent data values for each group (COLUMN_MAJOR), or the where the rows represent groups and the columns represent data values for each group (ROW_MAJOR). Use the CSV.setOrientation method to initialize the csv argument for the proper data orientation.

Parameters:

csv - An instance of an CSV object.

filename - The name of the file.

writeGroupDataset

public void writeGroupDataset(CSV csv,
                              java.lang.String filename,
                              boolean append)
