After upgrading, run update_cvpa_data() to refresh your
local cache: the cached question catalog from earlier versions is out of
date.
update_cvpa_data(questions = "all") has been
removed. Name the question codes you need (see
question_catalog()); it now errors with a pointer to the
full dataset.parquet in the cvpa_dataset
repository for anyone who wants everything.
wtd_vote() and gap_analysis() now
default to years = NULL, meaning every year in
data, instead of 1945:2023 and
1945:2022. The old defaults silently dropped any year after
2023 (and, for gap_analysis(), 2023 itself). Results on the
bundled vote_data are unchanged for
wtd_vote(); gap_analysis() now includes 2023.
Pass years explicitly to restore the old
behaviour.
The default cvpa.data_url is now
https://policyattitudes.ca/cp3_parquet/, hosted with the
project site, instead of the copy on quantoid.ca, which was out of date
and is no longer read by the package. The new data includes the merge of
ces_soim_009 into bri_soim_014 (same-sex
marriage; bri_soim_014 now covers the CES 1993, 1997, 2000,
2004, 2006 and 2008 surveys and has the wording “Support or oppose
allowing same-sex couples to marry”), and respondent ages recovered for
five Environics surveys.
question_catalog() now lists only questions and
surveys that have respondent-level data, so n_waves counts
only surveys that actually have data, and questions with no data (such
as env_intd_045) are no longer listed. Surveys with no
region variable cannot be weighted and are not included.
testthat suite (run offline against the
bundled example data) covering the data download and caching, the
question catalog, decoding, the weighted-share and gap-analysis
functions, the unofficial-data warnings and the legacy vote
functions.Every help page now has examples, and all of them run (none are
wrapped in \dontrun{} any more). The ones that need data
use a small bundled example dataset – four questions, with a random
sample of respondents from each survey year – through the new
cvpa_example_url(), in a temporary cache, so they run
offline and never touch your own cache. The example data is for
illustration only.
update_cvpa_data() now warns whenever
options(cvpa.data_url = ...) is anything other than the
official live data
(https://policyattitudes.ca/cp3_parquet/), and says how to
switch back. The functions that read the cache
(question_catalog(), question_data(),
question_response_labels()) also warn, once per session, if
the cache was downloaded from an unofficial source;
update_cvpa_data() records the source in a small
cvpa_source.txt file in the cache directory.
gap_analysis() and
response_gap_analysis() reported conf.low and
conf.high the wrong way round: the confidence interval for
diff (group 2 minus group 1) was negated but its limits
were not swapped, so conf.low was always larger than
conf.high. The interval itself was right and plots that
draw between the two values looked fine, but anything that treated
conf.low as the lower bound got the wrong number.
conf.low is now the lower limit and diff
always lies between the two. If you saved or published these two columns
from an earlier version, they are simply swapped: the old
conf.high is the correct lower limit and the old
conf.low the correct upper limit.
update_cvpa_data() no longer leaves a corrupt file
in the cache when a download fails. Downloads are written to a temporary
file and checked to be valid Parquet before they replace anything, so a
failed, truncated, or error-page download can’t overwrite a good cached
copy. A failure to download the catalog or code labels stops with an
error and leaves the cache untouched.
update_cvpa_data() skips a question whose file can’t
be downloaded, with a warning naming it, instead of stopping at the
first missing file. The return value gains a "skipped"
attribute listing those questions.
A local file:// mirror set through
options(cvpa.data_url = ...) now works; a cache-busting
query string was being appended to every URL.
Two question wordings (ces_dpin_016,
env_intd_012) no longer show their quotation marks repeated
several times over.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
