Maintenance release to restore the package to CRAN (the 0.5.0 version was archived on 2026-02-10 because the maintainer email was undeliverable) and to update for current dependency versions.
lwqs() now extracts the time-varying mixture effect and its standard error
through the documented predict() interface for mgcv/gamm4 fits, instead
of reading positionally from the list invisibly returned by plot.gam(). The
previous approach depended on undocumented element ordering and also drew a
plot as a side effect.ci_level argument to lwqs() (default 0.95); the confidence band is
now built from the corresponding normal critical value rather than a
hard-coded 1.96.ylim(-1, 1) on the effect plot, which could silently
clip effects and confidence bands that fell outside that range.data, timevar, outcome, and ID with
informative error messages.gWQS argument b_constr
(b1_constr is deprecated in current gWQS).ggplot2 size aesthetic with linewidth for line
geoms.geom_smooth() is now called with an explicit formula = y ~ x.
