Calculate frequencies.

1 2	prodcalc(data, formula, divider = mosaic(), cascade = 0, scale_max = TRUE, na.rm = FALSE)

`data`	input data frame
`formula`	formula specifying display of plot
`divider`	divider function
`cascade`	cascading amount, per nested layer
`scale_max`	Logical vector of length 1. If `TRUE` maximum values within each nested layer will be scaled to take up all available space. If `FALSE`, areas will be comparable between nested layers.
`na.rm`	Logical vector of length 1 - should missing levels be silently removed?
