adorn_ns: Add underlying Ns to a tabyl displaying percentages.

Description

This function adds back the underlying Ns to a tabyl whose percentages were calculated using adorn_percentages(), to display the Ns and percentages together. You can also call it on a non-tabyl data.frame to which you wish to append Ns.

Usage

adorn_ns(dat, position = "rear", ns = attr(dat, "core"), ...)

Arguments

dat

a data.frame of class tabyl that has had adorn_percentages and/or adorn_pct_formatting called on it. If given a list of data.frames, this function will apply itself to each data.frame in the list (designed for 3-way tabyl lists).

position

should the N go in the front, or in the rear, of the percentage?

ns

the Ns to append. The default is the "core" attribute of the input tabyl dat, where the original Ns of a two-way tabyl are stored. However, if you need to modify the numbers, e.g., to format 4000 as 4,000 or 4k, you can do that separately and supply the formatted result here.

...

columns to adorn. This takes a tidyselect specification. By default, all columns are adorned except for the first column and columns not of class numeric, but this allows you to manually specify which columns should be adorned, for use on a data.frame that does not result from a call to tabyl.

Value

a data.frame with Ns appended

Examples

# NOT RUN {
mtcars %>%
  tabyl(am, cyl) %>%
  adorn_percentages("col") %>%
  adorn_pct_formatting() %>%
  adorn_ns(position = "front")
# }
