pc_prop()returnedNAwithout much further explanation if any of the queries were not positive integers. The updated function attempts to coerce queries to positive integers, only progresses valid queries, and prints informative messages along the way if verbose messages are enabled.
- The
nist_rifunction now returns a column with the CAS number to facilitate querying of multiple retention index tables. - The
nist_rifunction can now take multiple arguments fortype,polarityandtemp_prog. - CAS numbers are automatically reformatted using
as.casinbcpc_query,cts_convert,get_etoxid,fn_percept,get_cid, andsrs_query. - The

"type"argument inci_query()andaw_query()has been changed to"from"for consistency with other functions. fn_percept()andcts_compinfo()now have"query"and"from"arguments for consistency with other functions.- Possible values for
"from"have been made more consistent across functions. pc_synonyms(),cts_convert(),cir_query()have been changed to use thematchargument instead ofchoicesfor consistency with other functions.get_etoxid()output changed slightly so that the matched chemical name string no longer includes the etoxid in parentheses.is.cas()is now vectorized.

from =argument. - nist_ri() now can search by name, InChI, InChIKey, or CAS. The

- All
get_*()functions now output tibbles with a column for the query and a column for the retrieved ID. - Changes to arguments in
get_*()functions to make them more consistent. - aw_idx.rda is no longer included in the package as a data set. Instead, it is built by build_aw_idx() to tempdir().
