get_chebiid {webchem} | R Documentation |
Retrieve Lite Entity (identifiers) from ChEBI
Description
Returns a data.frame with a ChEBI entity ID (chebiid), a ChEBI entity name (chebiasciiname), a search score (searchscore) and stars (stars) using the SOAP protocol: https://www.ebi.ac.uk/chebi/webServices.do
Usage
get_chebiid(
query,
from = c("all", "chebi id", "chebi name", "definition", "name", "iupac name",
"citations", "registry numbers", "manual xrefs", "automatic xrefs", "formula",
"mass", "monoisotopic mass", "charge", "inchi", "inchikey", "smiles", "species"),
match = c("all", "best", "first", "ask", "na"),
max_res = 200,
stars = c("all", "two only", "three only"),
verbose = getOption("verbose"),
...
)
Arguments
query |
character; search term. |
from |
character; type of input. |
match |
character; How should multiple hits be handled?, |
max_res |
integer; maximum number of results to be retrieved from the web service |
stars |
character; "three only" restricts results to those manualy annotated by the ChEBI team. |
verbose |
logical; should a verbose output be printed on the console? |
... |
currently unused |
Value
returns a list of data.frames containing a chebiid, a chebiasciiname, a searchscore and stars if matches were found. If not, data.frame(NA) is returned
