If x is a vector, then the grouping variables must contain one row for each element of x. If x is a matrix, then the grouping variables must contain one row for each column of x. Groups that contain a missing value (NaN), an empty character vector, or an empty string in a grouping variable are omitted, and are not counted in the number of groups considered by other parameters.
