Visualizing Interval-Valued Data Using 'ggplot2'

github.com/hanmingwu1103/gginterval ↗

Interval-valued data plotting, spending 2026 making its function names and examples survive CRAN.

◆Current state
ggInterval visualizes symbolic interval-valued data — observations recorded as ranges rather than points — with a family of plot functions in the ggplot2 idiom. The plot catalogue grew most recently with interval correlation heatmaps and interval line plots compatible with time-series input. The three releases before that were corrections: seven plot functions renamed for consistency, examples switched from dontrun to donttest at CRAN's request, and a vignette rewritten to demonstrate every function in one place.
◆Where it's heading
The package is consolidating an interface that had drifted. Renaming seven functions in a single release is the clearest signal — the naming was inconsistent enough to be worth breaking, and the vignette rewrite that followed suggests discoverability was the underlying complaint. Underneath that, the additions are steady and narrow: each release brings interval-aware versions of plot types that already exist for point data, which is the whole premise of the package.
◆Prediction
The pattern of porting one more standard plot type into interval-aware form each release is the most likely continuation; the tsplot compatibility in the latest version hints that time-series interval data is the direction attracting attention.

    Interval correlation heatmaps and time-series-compatible line plots

    Two new plot types join the catalogue, with the line plot accepting time-series input. It continues the package's core pattern of bringing standard visualizations into interval-aware form, and it is the first release in the window that adds capability rather than repairing presentation.

    Examples switched to donttest per CRAN review

    A CRAN review response changing how three examples are marked, plus a malformed example fixed and documentation regenerated. Nothing user-facing beyond examples that now run under check.

    Vignette rewritten to cover every plot function

    A self-contained introduction replacing the previous vignette, along with a stale index entry and a missing match.arg() in the interval correlation function. Documentation work following directly on the function renames of the previous release.

    Seven plot functions renamed for consistency

    A deliberate break to make the function family read consistently, alongside a ggplot2 aesthetic mapping fix in the scatterplot. Renaming seven exported functions at once is the kind of decision taken while a package is still small enough to afford it, and the documentation work in the next two releases is its direct consequence.
