Constructor for HmdbEntry instance

Description

Constructor for HmdbEntry instance

Usage

HmdbEntry(
  prefix = "http://www.hmdb.ca/metabolites/",
  id = "HMDB0000001",
  keepFull = TRUE
)

Arguments

prefix

character(1) URL of HMDB source accepting queries for XML documents
id

character(1) HMDB identifier tag
keepFull

logical(1) indicating that entire parsed XML will be retained

Value

instance of HmdbEntry, or a list

Note

The XML returned by hmdb.ca can have different structures for different metabolites. If the mapping form XML to list is not as anticipated for a given metabolite, the xmlToList result is returned with a warning. Such entries should be reported to the hmdbQuery maintainer for map revision.

Examples
