getsynonyms: Get PubChem Compound ID's and Synonyms
In rpubchem: An Interface to the PubChem Collection

Description Usage Arguments Details Value Author(s) See Also

PubChem allows one to obtain the compound ID's and synonyms of compounds that match a search string. This function uses the PubChem Power User Gateway (PUG) REST API to supply a character vector of one or more compound names and return the compound ID's and synonyms of matching compounds. Additional information on compounds can be obtained using the get.cid function.

1	get.synonyms(name, idtype = NULL, quiet=TRUE)

`name`	A vector of one or more compound names
`idtype`	The default value of `NULL` indicates that `name` should be considered a compound name. Alternative values are `inchikey` or `cid`, in which case `name` should be an InChI key or a Pubchem CID
`quiet`	If `FALSE`, output is verbose

Processing a large number of compounds can take a long time. The PUG REST API is not designed for very large volumes (millions) of requests. In order to avoid overloading the PubChem servers, this function is limited to 5 requests per second.

A data.frame with 4 columns:

`Name`	The compound name provided
`CID`	The compound ID
`Synonym`	Synonyms associated with the compound ID
`CAS`	Logical indicating whether the synonym is a CAS RN
