HistogramTools 0.4.1 (2026-05-06)

Addresses CRAN reviewer feedback on the 0.4.0 resubmission.

• DESCRIPTION: cite the methods implemented by the package (Rubner, Tomasi & Guibas 2000; Swain & Ballard 1991; Puzicha, Hofmann & Buhmann 1997; Scott 2015) using the <doi:...> / ISBN:... form CRAN expects.
• man/*.Rd: add a \value section to every exported function, giving the class and meaning of the returned object (or noting that the function is called for its side effect).
• man/dtrace.Rd: replace the \dontrun{} example, which required a live DTrace install, with a runnable one that parses the bundled inst/extdata/buildkernel-readsize-dtrace.txt sample.
• man/informationloss.Rd: unwrap the PlotKSDCC / PlotEMDCC calls from \dontrun{}; they run in well under five seconds.
• vignettes/HistogramTools.Rnw, vignettes/HistogramTools-quickref.Rnw: capture par() and options() at the top of each vignette and restore them at the end, so building the vignettes leaves the user’s graphics parameters and options unchanged.

HistogramTools 0.4.0 (2026-04-29)

Returns the package to CRAN after its 2024-04-20 archival.

• Fixes the package alias to match the package name (HistogramTools-package), the NOTE that triggered the archival.
• Switches Suggests/Enhances examples from if (require(RProtoBuf)) to if (requireNamespace("RProtoBuf", quietly = TRUE)) per CRAN policy 3.1.4, with RProtoBuf::P() fully qualified so example bodies don’t depend on attachment.
• Declares Encoding: UTF-8.
• Replaces the dead R-Forge URL with the GitHub repository (https://github.com/murraystokely/histogramtools) and adds BugReports.
• Drops stringr from Imports; the single str_trim call is replaced by base R trimws().
• inst/NEWS.Rd and ChangeLog are replaced by this NEWS.md. The detailed per-commit history remains in git log.

HistogramTools 0.3.2 (2015-07-29)

• NAMESPACE: add explicit importFrom for symbols in graphics, stats, and utils that R 3.3+ requires to be declared.
• R/histogram.R: replace stopifnot(require(RProtoBuf)) with requireNamespace() and an explicit error; use RProtoBuf::new() for message construction since new is generic in RProtoBuf.
• DESCRIPTION: drop the leading “This package” from the Description field per CRAN policy.

HistogramTools 0.3.1 (2014-08-26)

• DESCRIPTION: add Copyright and Authors@R fields.
• R/plot.R: fully qualify gdata::humanReadable so R CMD check on R-devel is clean when the conditionally-suggested gdata package is available.

HistogramTools 0.3 (2013-12-11)

• Move Hmisc from Depends to Imports.
• Significantly improved introduction vignette.
• Added ScaleHistograms().
• Added PlotRelativeFrequency() for plotting relative-frequency histograms.
• Added two-histogram distance and divergence measures: minkowski.dist, intersect.dist, kl.divergence, jeffrey.divergence.
• Added PreBinnedHistogram() for constructing histogram objects directly from a vector of breaks and counts.

HistogramTools 0.2 (2013-10-02)

• Moved RProtoBuf from Suggests to Enhances and made all uses conditional, so the package can be built and checked without it.
• Improved plot titles for PlotKSDCC and PlotEMDCC.
• Added a quick-reference vignette.
• Implemented histogram smoothing via Average Shifted Histograms from the ash package.
• Added PlotLog2ByteEcdf() and PlotLogTimeDurationEcdf() for ECDFs of data binned on power-of-two byte or log-scale time-duration boundaries.
• Removed the unused methods dependency and tightened up NAMESPACE imports/exports.

HistogramTools 0.1 (2013-09-13)

• Initial CRAN release.
