Set Logic for denominator subsetting

Source: R/count_bindings.R
set_denom_where.Rd

By default, denominators in count layers are subset based on the layer level where logic. In some cases this might not be correct. This functions allows the user to override this behavior and pass custom logic that will be used to subset the target dataset when calculating denominators for the layer.

Usage

set_denom_where(e, denom_where)

Arguments

e

A count_layer/shift_layer object

denom_where

An expression (i.e. syntax) to be used to subset the target dataset for calculating layer denominators. Supply as programming logic (i.e. x < 5 & y == 10). To remove the layer where parameter subsetting for the total row and thus the percentage denominators, pass 'TRUE' to this function.

Value

The modified Tplyr layer object

Examples

library(magrittr)
t10 <- tplyr_table(mtcars, gear) %>%
  add_layer(
    group_count(cyl, where = cyl != 6) %>%
    set_denom_where(TRUE)
    # The denominators will be based on all of the values, including 6
  ) %>%
 build()
