newmark 1.10.0

• New function integrateDnHazard(): the annual rate at which the Newmark displacement of a sliding mass with a fixed yield coefficient exceeds a threshold, integrated over one site's rock hazard curves with the site factor, the displacement regressions and their weights; it reports the Poisson probability over the exposure, the contribution of a band of return periods, a bound of the rare tail beyond the curves, the calibration range of the yield coefficient of each model and the numerical diagnostics of its quadratures. The command exposes it as the other operations of the displacement family.
• A tables argument given as a JSON array whose members are all file references is decoded like the object form; it was refused as if it were neither an array nor an object of tables.
• A file that an argument of the command refers to and that does not exist is a usage error, exit 2 with the newmark: line alone, as an unreadable referenced .json file already was; it exited 1 as a failed operation.
• sampleSoilLayers() counts the layers of a column as the ceiling of its height over the layer thickness with a stated rounding tolerance. The quotient of two decimal lengths can land a few units of double precision above an integer, as with 2.1 m divided by 0.3 m, and the column got one layer more than its height holds. Only a quotient that exceeds an integer by at most four times the double-precision epsilon, relative to its value, changes its count.
• The tests of the numerical periods and roots that compare two equal evaluations accept a difference in the last digit: under the Intel MKL library the two evaluations differ there, as CRAN's additional check of 1.9.0 showed.
• The tests that reproduce the products of one hundred realizations byte for byte, the dense quadratures of integrateDnHazard() and the steep upper tail of integrateSiteSpectrum() run outside CRAN, in continuous integration and locally; on CRAN's Windows server the whole check took more than ten minutes with them.

newmark 1.9.1

• The library signals its notes, progress and warnings as classed conditions of the AOM family (moduleNote, moduleProgress and moduleWarning) with the fields operation, phase, unit, path, count and total. Their texts lose the prefixes dry run:, <step>:, evaluateSiteFactor: and >>, and the kmax warnings name their table in parentheses. A failure after a publication of processProject() has the classes newmarkPartialPublication, modulePartialPublication and moduleFailure. The command reads its arguments from the launcher, whose renderer writes these conditions on stderr and takes --verbose and --quiet.
• The private predicates .isName() and .isKmaxIdentifier() become one predicate, .isIdentifier(), and .dnDemandsOK() and .hasKmaxDemands() become .hasDemands(). They are internal; no exported function changes its behavior.
• The test files are renamed to the test-<function>.R form; for example, test-kmax-table.R is now test-buildKmaxTable.R.
• The package help page, ?newmark, describes all the families of exported functions.
• New dataset VancouverSpectra: the uniform hazard spectra of the 2020 National Building Code of Canada for Vancouver on rock, from the seismic hazard tool of Natural Resources Canada. The examples of convertAEP(), evaluateUniformHazard() and evaluateSiteSa() read it.
• New function listDisplacementFamilies(): the families of displacement models (ensemble, rigid and flexible) that the displacement and kmax tables summarize as trees, each with the identifiers of its models. The command line runs it as the operation of the same name.
• ?newmark loses the package name from its title. The help pages of estimatePGV() and estimateAI() cite Verri Kozlowski (2023), the source of the rock records their relations were fitted on. On CRAN, the tests that repeat a step of processProject() skip; one run of each step and the dry run still execute there.
• Mw.gmdp takes one magnitude for every demand, as before, or an object that names each return period of TR.gmdp and MCE with its own magnitude; buildDnTables() takes the same as a named vector in Mw. The DnTable step applies the magnitude of each demand. A contract with one magnitude gives the same tables as before.
• newmark doctor prints one JSON report of the installation, as every module of the family does: schema, package, version, summary and the checks library, exports, packages, tools and receipt, each with name, required, status and detail; it exits 1 when a required check fails, and doctor --help lists the checks. describeModule(resources) returns that report. newmark --version prints two lines, the package with its version and the build commit.
• A .json file that an argument of the command refers to and that cannot be read as JSON is a usage error, exit 2 with the newmark: line alone, as an invalid INPUT.json already was; it exited 1 as a failed operation.
• The accumulations that feed a discrete choice, a rounding or a cut in the site mixture, the site spectrum, the soil profile and the PGA and displacement tables sum in plain double on every platform, as the kmax, displacement and mixture summaries have since 1.9.0; the tables are unchanged on macOS, where the reference products were recorded.

newmark 1.9.0 (2026-10-24)

This release replaces the interface of newmark 1.3.0, the previous CRAN release. The package was rebuilt around functions named by what they compute, one family at a time: soil profiles, site response, hazard inputs, displacements and the pseudostatic coefficient.

Breaking changes

• The 34 exports of 1.3.0 are gone. The two that had survived as compatibility adapters, buildGMDP() and fitSaFMixture(), are retired in this release: fitSaFMixture() is replaced by integrateSiteMixture(), and the hazard inputs that buildGMDP() staged are read with readHazardWorkbook(), convertAEP() and evaluateUniformHazard().
• Removed exports of 1.3.0 with no function of the same name: approx.spline, buildQSpline, checkUHS, designUHS, Dn_AM88, Dn_BM17, Dn_BM19, Dn_BT07, Dn_JB07, Dn_SR08, F_ST17, F_ST20, fitDnCurve, fitDnModel, fitDnScenario, fitDnScenarios, fitKmaxScenario, fitKmaxScenarios, fitModel.Ts, fitSaF, geSiteTable, getCylinderRoots, getDnKy, getKyLimits, getSiteProperties, interpolateSaTable, invertDnDraws, rhoBJ, SaF_ST17, sampleSaCorr, SIDtoVs30, Vs30toSID.
• The site amplification models ST17 and ST20 are selected through the model argument of evaluateSiteFactor() and the site response functions. The displacement models AM88, BM17, BM19, BT07, JB07 and SR08 are selected through selectDisplacementModels() and evaluated by evaluateRigidDisplacement(), evaluateFlexibleDisplacement() and solveKmax().
• The dataset SiteTable is no longer shipped. CylinderRoots, ShearModelParameters and SiteClass remain.
• Depends is R (>= 4.2). digest, Hmisc, randomForest, rpart, stringr and triangle are no longer imported; readxl moves to Suggests; jsonlite and parallel are imported.
