If set to TRUE, then the data frame's row.names are appended to the left of the data frame with the name "id". If set to quoted character string, the row.names are added using the character string as its name. If set to FALSE row.names are lost.

This is a convenience function in the car package for exporting (writing) a data frame to a file in a wide variety of formats including csv, Microsoft Excel. It optionally allows converting the row.names for the data frame to a column before writing. It then calls export in the rio package. That function in turn uses many other packages and functions for writing the function to a file.
