These functions help search for mappings between an a concept and a Metathesaurus identifier in the MRCONSO Table. All queries are cached using the R.cache package for quicker retrieval of the more computationally expensive searches.
| conn | Postgres connection |
|---|---|
| schema | Metathesaurus schema |
| concept | Concept to be searched |
| match_case | If TRUE, both the MRCONSO STR column and the `concept` argument are converted to lowercase. |
| cache_only | If TRUE, only the cache is loaded and database querying is skipped. If a cache did not exist for the query, a NULL will be returned. |
| skip_cache | If TRUE, the cache is skipped altogether. The database is directly queried and the resultset is not cached. |
| override_cache | If TRUE, the cache is not loaded, the database is directly queried and the resultset is cached, overwriting any existing cache that may have been present. |
Dataframe of 0 or more rows of all the fields in the MRCONSO Table.
