)

Arguments

query

character; InChIkey.

from

character; currently only accepts "inchikey".

verbose

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

inchikey

deprecated

Value

Examples

if (FALSE) { # \dontrun{
# might fail if API is not available
out <- cts_compinfo("XEFQLINVKFYRCS-UHFFFAOYSA-N")
# = Triclosan
str(out)
out[[1]][1:5]

### multiple inputs
inchikeys <- c("XEFQLINVKFYRCS-UHFFFAOYSA-N","BSYNRYMUTXBXSQ-UHFFFAOYSA-N" )
out2 <- cts_compinfo(inchikeys)
str(out2)
# a list of two
# extract molecular weight
sapply(out2, function(y) y$molweight)
} # }
