Renames variables in a data frame by adding the desired extensions to the original names.
This can be useful if you want to use pre summarised data with any_table(), which needs
the value variables to have the statistic extensions.
Arguments
- data_frame
The data frame in which variables should gain extensions to their name.
- from
The position of the variable inside the data frame at which to start the renaming.
- extensions
The extensions to add.
- reuse
"none" by default, meaning only the provided extensions will be set. E.g. if there are two extensions provided, two variables will be renamed. If "last", the last provided extension will be used for every following variable until the end of the data frame. If "repeat", the provided extensions will be repeated from the first one for every following variable until the end of the data frame.
Examples
# Example data frame
my_data <- dummy_data(1000)
# Add extensions to variable names
new_names1 <- my_data |> add_extension(5, c("sum", "pct"))
new_names2 <- my_data |> add_extension(5, c("sum", "pct"), reuse = "last")
new_names3 <- my_data |> add_extension(5, c("sum", "pct"), reuse = "alternate")
