weightCol = "LiveWeightKG",
cellCols = c("Metier5", "quarter", "Area"),
complete = F
)Arguments
- data

- weightCol
character() column in 'data' that contains catch weights
- cellCols
character() vector of columns in 'data' defining cells
- complete
logical() whether all combinations of the columns in cellCols should be tabulated, even if they contain no catch.
Value
