Returns the path where downloaded CPS data files are stored. The default is
~/cps_data, which expands to your home directory on any platform.
Details
To use a different location persistently, add this to your .Rprofile:
options(cpsvote.datadir = "~/my/path/to/cps_data")Any path set this way will be used automatically by cps_load_basic(),
cps_read(), and cps_download_data() without needing to pass datadir
each time.
