Function to add a row number variable to a data frame.

Description

Row numbers will be a variable which is an integer, unlike rownames_to_column which adds a character variable.

Usage

add_row_numbers(df, name = "row_number", zero_based = FALSE)

Arguments

df	Data frame to be transformed.
name	Name of variable to use. add_row_numbers will silently drop an existing variable of the same name if present in df.
zero_based	Should the numbering start at 0 rather than 1? Default is FALSE.
