```
tbl_continuous(
data,
variable,
include = everything(),
digits = NULL,
by = NULL,
statistic = NULL,
label = NULL
)
```

- data
A data frame

- variable
Variable name of the continuous column to be summarized

- include
variables to include in the summary table. Default is

`everything()`

- digits
List of formulas specifying the number of decimal places to round continuous summary statistics. If not specified, an appropriate number of decimals to round statistics will be guessed based on the the variable's distribution.

- by
A column name (quoted or unquoted) in

`data`

. Summary statistics will be calculated separately for each level of the`by`

variable (e.g.`by = trt`

). If`NULL`

, summary statistics are calculated using all observations. To stratify a table by two or more variables, use`tbl_strata()`

- statistic
List of formulas specifying types of summary statistics to display for each variable. The default is

`everything() ~ {median} ({p25}, {p75})`

- label
List of formulas specifying variables labels, e.g.

`list(age ~ "Age", stage ~ "Path T Stage")`

. If a variable's label is not specified here, the label attribute (`attr(data$age, "label")`

) is used. If attribute label is`NULL`

, the variable name will be used.
