make_willingness_utility_group_by(
  x,
  money_pay_var_string,
  group_var_string,
  jump = 1,
  var_min = NA,
  var_max = NA
)

money_pay_var_string	Target variable name as string, represents money.
group_var_string	the grouping variable as string for which the process needs to be repeated
jump	by default ==1 jumps on the cost axis
var_min	by default = NA, allows you to specify the minimal value

Examples

quality_assurance <- data.frame(
ID = 1:500,
money_willing_to_pay = sample(seq(0,20,5), size = 500, replace = T),
year = sample(c("2018", "2019", "2020"), size = 500, replace = T))

quality_assurance %>%
  make_willingness_utility_group_by(money_pay_var_string = "money_willing_to_pay",
                                   group_var_string = "year")
