getId: Find a given taxa by name

In sherrillmix/taxonomizr: Functions to Work with NCBI Accessions and Taxonomy

Find a given taxa by name

Description

Find a taxa by string in the NCBI taxonomy. Note that NCBI species are stored as Genus species e.g. "Bos taurus". Ambiguous taxa names will return a comma concatenated string e.g. "123,234" and generate a warning.

Usage

getId(taxa, sqlFile = "nameNode.sqlite", onlyScientific = TRUE)

Arguments

taxa	a vector of taxonomic names
sqlFile	a string giving the path to a SQLite file containing a names tables
onlyScientific	If TRUE then only match to scientific names. If FALSE use all names in database for matching (potentially increasing ambiguous matches).

Value

a vector of character strings giving taxa IDs (potentially comma concatenated for any taxa with ambiguous names)
