Ordering of steps

In the recipes package, there are no constraints on the order in which steps are added to the recipe; you as a user are free to apply steps in the order appropriate to your data preprocessing needs. However, the order of steps matters and there are some general suggestions that you should consider.

Transforming a variable

Handling levels in categorical data

The order of steps for handling categorical levels is important, because each step sets levels for the next step to use as input. These steps create factor output, even if the input is of character type.

Dummy variables

Recipes do not automatically create dummy variables (unlike most formula methods).

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
