Show the taxadb directory
Details
NOTE: after upgrading duckdb, a user may need to delete any
existing databases created with the previous version. An efficient
way to do so is unlink(taxadb::taxadb_dir(), TRUE).
Examples
## show the directory
taxadb_dir()
#> [1] "/tmp/RtmpSoAtFu/taxadb"
## Purge the local db
unlink(taxadb::taxadb_dir(), TRUE)
