data |
A data.frame or factor. In the first case, |
maximum_levels |
Numeric. The maximum number of levels allowed per factor |
A factor with at most maximum_levels
, or a data.frame where each factor matches that requirement
factor
: Group infrequent levels in a factor. Takes a factor, and if that factor has more than 'maximum_levels', it makes a table of level frequencies. The top (maximum_levels-1) are left unchanged, all less frequent levels are grouped into the level "other".
data.frame
: Takes a data.frame, and applies group_levels.factor to each column
list
: Takes a list of data.frames and applies group_levels.data.frame
to each
