write_sas()
creates sas7bdat files. Unfortunately the SAS file format is
complex and undocumented, so write_sas()
is unreliable and in most cases
SAS will not read files that it produces.
write_xpt()
writes files in the open SAS transport format, which has
limitations but will be reliably read by SAS.
write_sas(data, path)
Data frame to write.
Path to file where the data will be written.
