tabyl | R Documentation |
A fully-featured alternative to table()
. Results are data.frames and can be
formatted and enhanced with janitor's family of adorn_
functions.
Specify a data.frame
and the one, two, or three unquoted column names you
want to tabulate. Three variables generates a list of 2-way tabyls,
split by the third variable.
Alternatively, you can tabulate a single variable that isn't in a data.frame
by calling tabyl()
on a vector, e.g., tabyl(mtcars$gear)
.
tabyl(dat, ...)
## Default S3 method:
tabyl(dat, show_na = TRUE, show_missing_levels = TRUE, ...)
## S3 method for class 'data.frame'
tabyl(dat, var1, var2, var3, show_na = TRUE, show_missing_levels = TRUE, ...)
dat |
A |
... |
Additional arguments passed to methods. |
show_na |
Should counts of |
show_missing_levels |
Should counts of missing levels of factors be displayed? These will be rows and/or columns of zeroes. Useful for keeping consistent output dimensions even when certain factor levels may not be present in the data. |
var1 |
The column name of the first variable. |
var2 |
(optional) the column name of the second variable (the rows in a 2-way tabulation). |
var3 |
(optional) the column name of the third variable (the list in a 3-way tabulation). |
A data.frame
with frequencies and percentages of the tabulated variable(s).
A 3-way tabulation returns a list of data frames.
tabyl(mtcars, cyl)
tabyl(mtcars, cyl, gear)
tabyl(mtcars, cyl, gear, am)
# or using the %>% pipe
mtcars %>%
tabyl(cyl, gear)
# illustrating show_na functionality:
my_cars <- rbind(mtcars, rep(NA, 11))
my_cars %>% tabyl(cyl)
my_cars %>% tabyl(cyl, show_na = FALSE)
# Calling on a single vector not in a data.frame:
val <- c("hi", "med", "med", "lo")
tabyl(val)
