rblimp 1.2.0 (2026-05-18)
- New
install_blimp() and uninstall_blimp() functions let rblimp
download and manage the Blimp engine directly, without going through
the system installer. Installs to a user-writable directory
(~/.blimp/ on macOS and Linux, %LOCALAPPDATA%/Blimp/ on Windows),
overridable via the R_BLIMP_HOME environment variable.
- When
rblimp() / rblimp_source() is run in an interactive session
and Blimp is not installed, the user is now offered the option to
install it via install_blimp() on the spot.
detect_blimp() gained a prompt = argument; defaults to TRUE for
the new interactive install offer.
update_blimp() now routes based on install type: for managed installs
it checks the manifest version first and re-downloads only when a newer
version is available; system installs still launch the Blimp Updater
application.
- Update version checks now use a JSON manifest endpoint
(
https://updates.blimpstats.com/v1/blimp_base.json) instead of
parsing the plain-text changelog. Manifest URL is overridable via
the R_BLIMP_MANIFEST_URL environment variable.
- New
R_BLIMP_NO_UPDATE_CHECK environment variable disables automatic
update checks (alternative to options(check_blimp_update = FALSE)).
- New
R_BLIMP_PREVENT_INSTALL environment variable blocks
install_blimp() for locked-down environments.
rblimp 1.1.1
- Fixed a bug in
trace_plot() when called with specific parameters.
rblimp 1.1.0 (2026-04-14)
- Added an
as.array() method for blimp_obj that returns an
[iterations, chains, parameters] 3-D array compatible with bayesplot.
Supports a warmup = c("exclude", "include", "only") argument for
including burn-in draws; when warmup = "include" the returned array
carries an "n_warmup" attribute so it pipes directly into
bayesplot::mcmc_trace(arr, n_warmup = attr(arr, "n_warmup")).
- Added S3 methods registering
blimp_obj with the posterior package's
as_draws(), as_draws_array(), and as_draws_df() generics, unlocking
the posterior / bayesplot summary and plotting ecosystems. posterior
is a soft dependency (in Suggests).
- Trace plots now display rank-normalized split-Rhat (Vehtari et al., 2021)
instead of the basic PSRF, and fixed facet labels when plotting a subset
of parameters.
