Canonicalises user-supplied version strings for Census of Population.
Any string starting with a four-digit year is parsed flexibly: the file
type is detected by grepping for "hierarchical", "household", or "famil"
(defaulting to "individuals"), and CMA vs provincial by grepping for "cma".
The registry is then probed to find the correct canonical format for that
year (e.g. `"1971/households_cma"`, `"1986/households"`, or
`"2001 (households)"`).
Usage
pumf_resolve_version(series, version)
Arguments
- series
survey series acronym
- version
raw version string supplied by the caller, or `NULL`
Value
canonical version string (or `NULL` if `version` was `NULL`)
