Overview

About

Maintained by Frank E Harrell JrCRAN page ↗GitHub ↗Website ↗

Regression modeling, testing, estimation, validation, graphics, prediction, and typesetting by storing enhanced model design attributes in the fit. 'rms' is a collection of functions that assist with and streamline modeling. It also contains functions for binary and ordinal logistic regression models, ordinal models for continuous Y with a variety of distribution families, and the Buckley-James multiple regression model for right-censored responses, and implements penalized maximum likelihood estimation for logistic and ordinary linear models. 'rms' works with almost any regression model, but it was especially written to work with binary or ordinal regression models, Cox regression, accelerated failure time models, ordinary linear models, the Buckley-James model, generalized least squares for serially or spatially correlated observations, generalized linear models, and quantile regression.

Changes in 8.1-1

infoMxop: look for intercepts attribute in info if info matrix is not a 3-element list; don't look for a, b, ab if same pertains
lrm.fit, : add intercepts attribute to info.matrix if not a 3-element list; fixes bug with vcov when transx=TRUE
lrtest: corrected to use fit$stats['d.f.'] first
Help file importexport.Rd: changed possible values of type argument to match survival 3.8-5
prModFit as used by print.Gls: removed quote=FALSE passed to print as nlme::print correlation summary does this already; cleaned up some code; see https://github.com/harrelfe/rms/issues/166
ordParallel: fixed issue with wrong argument to GiniMd; see https://github.com/harrelfe/rms/issues/168
vcov.orm (also serves lrm): fixed issue with not utilizing full covariance matrix produced by robcov etc.; see https://github.com/harrelfe/rms/issues/167
inst/tests/ordinal-robcov.r: new test for above
inst/tests/Survival-orm-km.r: new test for agreement of ordinal and Kaplan-Meier survival estimates
Ocens2ord: added return value named ranges containing 3 vectors of ranges (overall, uncensored points, censored points), and if there is right censoring, an object rt_cens_beyond with elements newlevel and range
orm.fit, orm: also returns rt_cens_beyond
Survival.orm: reworked logic for right censoring to guarantee agreement with survival::survfit when there are no covariates

From NEWS in the release

Install

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

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

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

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("harrelfe/rms")

Development version from harrelfe/rms. Installs pak first if it is not already available.

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-rms

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

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-rms

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-rms

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
