Reads the UK Biobank codings file into R with all columns as type character.
Arguments
- path
Either
NULL, or a file path. If no file exists at this path, then it will be downloaded directly from the UK Biobank data showcase website to this location when the function is first called.
Details
By default, an attempt will be made to read from a file at the path specified
by an environmental variable named UKB_CODINGS (see
vignette('ukbwranglr') for further details), or if this variable is not
found then the data dictionary will be downloaded directly from the UK Biobank website
to tempdir() when the function is first called.
Examples
get_ukb_data_dict(
get_ukb_dummy("dummy_Codings.tsv", path_only = TRUE)
)
