Details

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.
