cs_control(
  datasources = vector(),
  order_by = "default",
  order_direction = "default",
  include_all = FALSE,
  complexity = "any",
  isotopic = "any"
)

Arguments

datasources

character; specifies the databases to query. Use cs_datasources() to retrieve available ChemSpider data sources.

order_by

character; specifies the sort order for the results. Valid values are "default", "recordId", "massDefect", "molecularWeight", "referenceCount", "dataSourceCount", "pubMedCount", "rscCount".

order_direction

character; specifies the sort order for the results. Valid values are "default", "ascending", "descending".

include_all

logical; see details.

complexity

character; see details. Valid values are "any" "single", "multiple".

isotopic

character; see details. Valid values are "any", "labeled", "unlabeled".

Details

The only function that currently uses databases is get_csid() and only when you query a CSID from a formula. This parameter is disregarded in all other queries.

Setting include_all to TRUE will consider records which contain all of the filter criteria specified in the request. Setting it to FALSE will consider records which contain any of the filter criteria.

A compound with a complexity of "multiple" has more than one disconnected system in it or a metal atom or ion.

Value

Returns a list of specified control options.

Note

This is a full list of all API control options. However, not all of these options are used in all functions. Each API uses a subset of these controls. The controls that are available for a given function are indicated within the documentation of the function.
