Data can be preprocessed according to Menzies guidelines

       mark | type  | nump | wordp |

       ?    |       |      |       | a column to ignore
------------|-------|------|-------|-------------------
dep    =    | klass |      |   X   | a label to predict
       +    | more  |   X  |       | a goal to maximize
       -    | less  |   X  |       | a goal to minimize
------------|-------|------|-------|-------------------
indep  $    | num   |   X  |       | non-goal number 
       else | term  |      |   X   | non-goal non-number

Example if we consider weather dataset:

#data/weather1.csv
outlook,        # forecast
?+$temperature, # degrees Farenheit,
-$humidity,     # % of dewpoint
windy,          # boolean
=play           # goal

The header can be formatted in form of:

outlook,        # forecast
?+$temperature, # degrees Farenheit,
-$humidity,     # % of dewpoint
windy,          # boolean
=play           # goal
