Convert Ids using Chemical Translation Service (CTS), see http://cts.fiehnlab.ucdavis.edu/

Usage

cts_convert(
  query,
  from,
  to,
  match = c("all", "first", "ask", "na"),
  verbose = getOption("verbose"),
  choices = NULL,
  ...
)

Arguments

query

character; query ID.

from

character; type of query ID, e.g. 'Chemical Name' , 'InChIKey', 'PubChem CID', 'ChemSpider', 'CAS'.

to

character; type to convert to.

match

character; How should multiple hits be handled? "all" returns all matches, "first" returns only the first result, "ask" enters an interactive mode and the user is asked for input, "na" returns NA if multiple hits are found.

verbose

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

choices

deprecated. Use the match argument instead.

...

Value

a list of character vectors or if choices is used, then a single named vector.

Examples

if (FALSE) { # \dontrun{
# might fail if API is not available
cts_convert("XEFQLINVKFYRCS-UHFFFAOYSA-N", "inchikey", "Chemical Name")

### multiple inputs
keys <- c("XEFQLINVKFYRCS-UHFFFAOYSA-N", "VLKZOEOYAKHREP-UHFFFAOYSA-N")
cts_convert(keys, "inchikey", "cas")
} # }
