Splitting datasets in groups given by factors
Splits data sets of compositions in groups given by factors, and gives the same class as the data to the result.

x |
a dataset or a single vector of some type |
f |
a factor that defines the grouping or a list of factors |
drop |
drop=FALSE also gives (empty) datsets for empty categories |
... |
Further arguments passed to split.default. Currently (and probably) without any use. |
a list of objects of the same type as x.
