Overview

About

Maintained by Kaifeng LuCRAN page ↗GitHub ↗Website ↗Issues ↗

Implements rank preserving structural failure time model (RPSFTM), iterative parameter estimation (IPE), inverse probability of censoring weights (IPCW), marginal structural model (MSM), simple two-stage estimation (TSEsimp), and improved two-stage estimation with g-estimation (TSEgest) methods for treatment switching in randomized clinical trials.

Changes in 0.2.8

added summary methods for rpsftm, ipe, tsesimp, tsegest, ipcw, and msm with analysis populations, ordered TSD 24 reporting checklists, model parameter estimates, treatment effect estimates, weight summaries where applicable, and bootstrap summaries
added matched function calls to rpsftm, ipe, tsesimp, tsegest, ipcw, and msm output; MSM summaries distinguish exclusion of post-switching data from switching models and inclusion of post-switching data in the weighted outcome model
expanded rpsftm, ipe, tsesimp, tsegest, ipcw, and msm summaries with guidance to inspect relevant model diagnostics and plots, alongside reporting items requiring external justification or separately fitted sensitivity analyses
added pre-filter missingness summaries for AFT-model covariates in tsesimp and switching-model covariates in tsegest, ipcw, and msm, grouped by treatment arm and relevant model candidates
added p_kmstar to plot.ipe and added p_km_switch to plot.tsesimp and plot.tsegest
added data_switch and km_switch to tsesimp output
added a small positive value to avoid zero time in survival_analysis.cpp

Install

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

install.packages("trtswitch", 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("kaifenglu/trtswitch")

Development version from kaifenglu/trtswitch. 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-trtswitch

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-trtswitch

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-trtswitch

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.
