The data is downloaded to the directory specified by the dir parameter. Note
that if you specified a directory different from the default, you will need to set options(labNorm.dir = dir) in order for the package to use the downloaded data in future sessions.
Default directories are:
Unix: ~/.local/share/LabNorm
Mac OS X: ~/Library/Application Support/LabNorm
Win XP (not roaming): C:\\Documents and Settings\\<username>\\Data\\<AppAuthor>\\LabNorm
Win XP (roaming): C:\\Documents and Settings\\<username>\\Local Settings\\Data\\<AppAuthor>\\LabNorm
the directory to download the data to. If NULL and the user approves, the data will be downloaded to the package directory, using rappdirs::user_data_dir("labnorm"), otherwise - a temporary directory would be used.
