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

Description

Compute the proportion of items (like dplyr::add_count() does with number of appearances)

Usage

add_prop(x, ..., leave_n = FALSE, name = "prop")

Arguments

x	a tbl() to compute proportions
...	Variables to group by
leave_n	if TRUE will also generate a column named n4prop (FALSE by default).
name	The output column name. If omitted, it will be prop.

Value

A tbl, grouped the same way as x.

Examples

# Without any grouping, just calc proportions
mtcars %>% add_prop(cyl)
# Number of variables
mtcars %>% add_prop(cyl, vs)
# To compute the proportions relative to a variable, use a group_by
mtcars %>% group_by(am) %>% add_prop(cyl, vs)
