remove_names(.data)
names_to_column(.data, var = "name")
id_to_column(.data, var = "id")a Ranges object
Name of column to use for names
Returns a Ranges object with empty names
The function names_to_column() and id_to_column() always places
var as the first column in mcols(.data), shifting all other columns
to the left. The id_to_column() creates a column with sequential row
identifiers starting at 1, it will also remove any existing names.
