Overview

About

Maintained by Dipankor DhruboFirst published 2026-05-111 releasesCRAN page ↗

Implements the MEC-TX (MEchanistic Clustering - Treatment eXposure) framework for encoding, clustering, and survival analysis of real-world oncology treatment timelines. Provides functions for normalising medication records, computing treatment intervals, performing k-means clustering in PCA space, assigning line-of-therapy labels, and comparing survival outcomes across treatment groups. Designed for use with registry-based cohorts such as the ORIEN AVATAR dataset. Methods follow the digital-twin framework described in Dhrubo and Spakowicz (2026) https://github.com/spakowiczlab/mec-tx. treatment timelines using the MEC-TX digital-twin framework.

Install

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

install.packages("mectx", 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-mectx

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-mectx

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-mectx
