The
Pff.save function saves the contents of the
Pff object to the disk to a PFF file with the name supplied by the string expression
pff_filename. Because Pff objects can be executed without saving them, this function is not necessary, but may be useful if you want a copy of your PFF file on the disk.
The function returns a logical value of 1 (true) if the PFF was successfully saved and 0 (false) otherwise.
