shapeSet

dataSet

"data.table" or "numerical_matrix" (default to data.table)

finalForm

numeric, threshold such that a numerical column is transformed into
 a factor whenever its number of unique modalities is smaller or equal to
<code>thresh</code> (default to 10)

thresh

verbose

Prepare a data.table by: 
- transforming numeric variables into factors whenever they take less than <code>thresh</code> unique 
variables 
- transforming characters into factors 
- transforming logicals into binary integers 
- dropping constant columns 
- Sending the data.table to setAsNumericMatrix() (when finalForm == "numerical_matrix") will then allow 
you to get a numerical matrix usable by most Machine Learning Algorithms.

Do most of the painful data preparation for a data science project with a minimum amount of code; Take advantages of data.table efficiency and use some algorithmic trick in order to perform data preparation in a time and RAM efficient way.
