Returns the data frame with a new variable containing a running number.

Arguments

data_frame

The data frame in which to compute the running number.

var_name

The variable name of the running number.

By group in which to compute the running number per expression.

Examples

# Example data frame
my_data <- dummy_data(1000)

# Get row numbers
my_data <- my_data |> running_number()
my_data <- my_data |> running_number("row_number")

# Running number per variable expression
my_data <- my_data |> running_number(by = year)
