prop_multi: Compute the proportion of items for multiple non exclusive...

In sarid-ins/saridr: An R package for common tasks related to market research analysis via R

Description

Uses an id variable and groupings to calculate proportions in a multiple-choice (checkbox) scenario. I.e., answer proportions sum to more than 100

Usage

prop_multi(x, ..., idvar)

Arguments

x	a tbl() to compute proportions, this can be a grouped tbl()
...	Variables to group by.
idvar	the response id variable name as *string* (from which distinct respondents are to be computed)

Details

The function uses the variables names specificed in ..., to conduct a grouping

With a variable name in ..., calculates proportions cases of variable out of the total n unique idvar grouped by the variable. with a variable name in ... and pre grouped data, calc proportions cases of variable out of the total n unique idvar in the pregrouped cathegories grouped by the variable.

Value

A tbl, grouped the same way as x, with the proportions computed out of the distinct respondents. If x is grouped before the ..., the total of the distinct respondents will be calculated out of level of the previous groupings and not from the whole x data.

Examples

multi_choice <- tribble(~id, ~choice, ~yr,
                        1, "A", 2017,
                        1, "B", 2017,
                        1, "A", 2018,
                        2, "A", 2019,
                        2, "C", 2019,
                        2, "A", 2017,
                        3, "A", 2017,
                        3, "A", 2018)

# disregard the yr variable
multi_choice %>%
   prop_multi(choice, idvar = id)

# add the yr variable as a pre-grouping variable and use it as well
multi_choice %>%
   group_by(yr) %>%
   prop_multi(choice, idvar = "id")
