  query,
  from = c("name", "cas"),
  match = c("best", "all", "first", "na"),
  verbose = TRUE,
  ...
)

Arguments

query

character; searchterm, e.g. chemical name or CAS.

from

character; one of "name" or "cas".

match

character; match="all" returns all matches, match="first" the first one and match="best" (recommended) the hit with the lowest Levenshtein distance between query and matching synonym.

verbose

logical; should a verbose output be printed on the console?

...

currently not used.

Value

a named list of 73 entries, see https://www.pesticideinfo.org/about/overview.html for more information. If match="best" an additional entry match_score with the normalized Levenshtein distance (0 = perfect match, 1 = worst match).
