Create a two way data table
Usage
tbl_2var(
data,
formula,
row_pct = c("hide", "show"),
digits = 3,
caption = NULL,
na_rm = FALSE
)Arguments
- data
A data frame.
- formula
The variables to tabulate. Should be given in formula notation
var1~var2. Changing the order of the variables will swap the table axes.- row_pct
Should row percents be included in each cell? Defaults to "hide" with the only other possible value being "show".
- digits
The number of digits to round to. Defaults to 3.
- caption
An optional caption for the table. Defaults to
NULL, but a sensible default is provided within the function.- na_rm
Should missing values be removed? Defaults to FALSE.
Value
An object of class flextable. If in an interactive session, the table will be viewable immediately.
