Overview

About

Maintained by Alejandro Verri KozlowskiFirst published 2026-05-192 releasesCRAN page ↗

Implements a four-stage pipeline for probabilistic seismic performance analysis of slopes and embankments. The package takes a uniform-hazard spectrum at multiple return periods as input (any source) and produces: (1) synthetic soil profile generation and fundamental period estimation from USCS classification via Ishihara's small-strain shear-modulus model and the inhomogeneous truncated shear-beam theory of Gazetas and Dakoulas; (2) nonlinear site amplification using the NGA-East ergodic site-response models (Stewart et al. (2020) doi:10.1177/8755293019878185 and Hashash et al. (2020) doi:10.1177/8755293019878193, with the 2017 PEER-report generation retained as an option), with inter-period correlation via Baker & Jayaram (2008) doi:10.1193/1.2857544; (3) Monte Carlo ensemble of six empirical Newmark sliding-block displacement models (Ambraseys & Menu (1988) doi:10.1002/eqe.4290160704, Jibson (2007) doi:10.1016/j.enggeo.2007.01.013, Saygili & Rathje (2008) doi:10.1061/(ASCE)1090-0241(2008)134:6(790), Bray & Travasarou (2007) doi:10.1061/(ASCE)1090-0241(2007)133:4(381), Bray & Macedo (2017) doi:10.1016/j.soildyn.2017.05.024, and the Bray and Macedo shallow-crustal update) with coherent correlated draws; (4) log-log inversion to the performance-based seismic coefficient kmax at user-specified displacement targets. All outputs are 'data.table' objects.

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("newmark", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-newmark

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-newmark

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-newmark

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
