%description
Provides functionality for users who are learning R or the techniques of
data analysis.  Written as a collection of wrapper functions, the
'DTwrapper' package facilitates many core operations of data processing.
This is achieved with relatively few requirements about the order of the
processing steps or knowledge of specialized syntax.  'DTwrappers' creates
coding results along with translations to data.table's code.  This enables
users to benefit from the speed and efficiency of data.table's
calculations.  Furthermore, the package also provides the translated code
for educational purposes so that users can review working examples of
coding syntax and calculations.
