multiplexing in another functionCTGOV2CTGOV has retired on 2024-06-25 the classic website
and API used by ctrdata since 2015. To support users,
ctrdata now automatically translates and redirects queries
to the current website. This helps with automatically updating
previously loaded queries
(ctrLoadQueryIntoDb(querytoupdate = <n>)), manually
migrating queries and reproducible work on clinical trials information.
This new functionality in ctrdata translates a user’s
search query URL from the classic website into a query for the current
CTGOV website, for all search parameters. Since the
structure and format of data differs between data retrieved from the
current API and previously retrieved from the classic API,
ctrdata will continue to identify the current API as
register = "CTGOV2", to support the analysis stage. In
addition, ctrdata documentation continues to include
examples of analyses with CTGOV data, as this may have been
downloaded earlier.
CTIS has been relaunched on 2024-06-17, and
ctrdata has been fully updated to it. At the moment,
CTIS provides basic searches and no search query URL. To
support users, ctrdata includes an updated script that
extracts a user’s search parameters from the register search page to the
clipboard and into the browser URL bar. In addition, the script triggers
a search for trials when opening such a query URL, see
https://rfhb.github.io/ctrdata/#id_2-script-to-automatically-copy-users-query-from-web-browser.
File names of CTIS documents start now with the document
type,
e.g. SbjctInfaICF - L1 SIS and ICF NL for publication.pdf,
since the prefix (document source) introduced in version 1.18.0 is no
more applicable.
