bayesQRsurvey 0.2.1 (2026-04-03)

Bug fixes

• Fixed plot() crashing with "contrasts can be applied only to factors with 2 or more levels" when the model included factor predictors.
• Fixed DOI formatting in documentation (\url{doi:...} changed to \doi{...}), which caused help pages to fail to render.
• Fixed Anthro.rda compression to prevent R_decompress1 warnings during installation.

Data

• Anthro$sex is now stored as a factor (levels: 0 = girl, 1 = boy), so users no longer need to call as.factor() before fitting models.

Plot improvements

• Refined color palette across all plot types: cohesive blue accent (#2171B5) for lines, lighter blue (#6BAED6) for fills, muted red (#D6604D) for reference lines.
• Single-quantile fit plots now use a solid blue line instead of a single viridis color, and hide the redundant legend.
• Quantile-coefficient plots (type = "quantile") now always show the credible band and use the Greek tau symbol on the x-axis.
• Posterior density plots now display credible interval bounds as dotted vertical lines.
• Trace plots use thinner lines for better readability with dense MCMC chains.
• Legend labels for multiple quantiles now show only the numeric value (e.g., 0.100) with the legend title as the tau symbol, instead of repeating "tau = " on every entry.
• Titles are now left-aligned with a subtitle for parameter details (variable name, tau value) in a lighter style.
• Removed grey panel background for a cleaner look.

bayesQRsurvey 0.2.0 (2026-03-27)

• Added plotQuantileRegion for multivariate quantile regression.
• Redesigned print() and summary() methods for better readability.
• Improved aesthetics and parameter handling in plotting functions.
• Internal cleanup of compiled code and documentation updates.
