adorn_percentages: Convert a data.frame of counts to percentages.

Description

This function excludes the first column of the input data.frame, assuming that it contains a descriptive variable. If the input data.frame is not a tabyl, it will convert to one in order to preserve the underlying values in the core attribute.

Usage

adorn_percentages(dat, denominator = "row", na.rm = TRUE)

Arguments

dat

a tabyl or other data.frame with a tabyl-like layout. 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).

denominator

the direction to use for calculating percentages. One of "row", "col", or "all".

na.rm

should missing values (including NaN) be omitted from the calculations?

Value

Returns a data.frame of percentages, expressed as numeric values between 0 and 1.

Examples

# NOT RUN {
mtcars %>%
  tabyl(am, cyl) %>%
  adorn_percentages("col")

# calculates correctly even with totals column and/or row:
mtcars %>%
  tabyl(am, cyl) %>%
  adorn_totals("row") %>%
  adorn_percentages()
# }
