interactionR for Competitive Risk Models

This repository contains functions and demo scripts for extending the interactionR package to support competitive risk models, particularly using the crr() function from the cmprsk package. These tools allow for modeling interactions within cumulative incidence functions, providing more flexibility and depth in competitive risk analysis.

Features

• interactionR_crr.R: A function that enhances the interactionR functionality to work with crr() from the cmprsk package.
• interactionR_crr_demo.R: A demo script that demonstrates how to use the extended interactionR() function to perform competitive risk modeling with interaction terms.

Requirements

• R version >= 4.0.0
• cmprsk package (for fitting competing risks regression models)

To install the required packages, run the following command in R:

install.packages("cmprsk")

Usage

1. interactionR_crr.R:

   • This script contains the core function that extends interactionR() to handle competitive risk models.
   • To use, source the script and run the function as per your dataset.

2. interactionR_crr_demo.R:

   • This script provides a step-by-step guide on how to apply the interactionR function on a sample dataset using the competitive risk regression (crr) model.
   • Simply source the script and run it to see an example of the function in action.

Example Workflow

1. Source the main function:

source("interactionR_crr.R")

2. Run the demo script to see how the function works:

source("interactionR_crr_demo.R")
