Move row names to a column

A lightweight alternative to `tibble::rownames_to_column()` that does not require the tibble package. Prepends the row names of a data.frame as a new column.

Usage

rowname_to_column(data, var)

Arguments

data

A data.frame.

var

Character scalar. Name of the new column to hold row names.

Value

A data.frame with the same columns as `data` plus the new column `var` as the first column. Row names are removed.

Examples

df <- data.frame(x = 1:3, row.names = c("a", "b", "c"))
rowname_to_column(df, "id")
#>   id x
#> 1  a 1
#> 2  b 2
#> 3  c 3
