Special note
I am currently looking for someone who would be interested in becoming the official maintainer of the package. Advanced skill in R or previous package development experience is not necessary. I will be able to help out with code review, etc. Please comment on this issue if you are interested.
Summary
cattonum (“cat to num”) provides different ways to encode categorical features as numerics. Its goal is to be a one-stop shop for all categorical encoding needs. It includes the following:
- aggregate function encoding:
catto_aggregate() - dummy encoding:
catto_dummy() - frequency encoding:
catto_freq() - label encoding:
catto_label() - leave-one-out encoding:
catto_loo() - mean encoding:
catto_mean() - median encoding:
catto_median() - one-hot encoding:
catto_onehot()
There are many existing packages with which to encode categorical features, including (among others):
