reconcile_categories | R Documentation |
This is used internally by the builder method, sample_data
, to
ensure that the factors describing categorical variables in a data.frame or
sample_data object are free of extra levels that can plague downstream plots
analysis.
reconcile_categories(DFSM)
DFSM |
(Required). A |
A single data.frame
object. Even if the input argument is a sample_data
,
the return is a data.frame
. Because this is intended to be used internally by
the builder method, it cannot also call the builder function to re-build
the cleaned sample_data
.
