Normalizes max_removed_per_cond parameter for match_groups() and estimate_exhaustive().
.normalize_max_removed_per_cond(max_removed_per_cond, condition)
A named integer vector, containing the maximum number of subjects that can be removed from each group. Specify 0 for groups if you want to preserve all of their subjects. If you do not specify a value for a group, it defaults to 2 less than the group size. Values outside the valid range of 0..(N-1) (where N is the number of subjects in the group) are corrected without a warning.
A factor vector containing condition labels.
