Installation Guide

Back to Contents

You can install the rhap package in two ways:

• Option 1: Install directly from GitHub
  
• Option 2: Clone the repository (recommended for full access to project files)

Option 1: Direct Installation from GitHub

Prerequisites

Make sure the following software is installed:

• R: Download R
• RStudio (recommended IDE): Download RStudio

Install the Package

• Open RStudio

• Run the following in the R Console:

r install.packages("remotes") # Skip if already installed remotes::install_github("bc3LC/rhap")

Option 2: Clone the Repository (Recommended)

Cloning the repository is recommended if you want full access to the project structure, input files, and examples.

Prerequisites

Make sure the following software is installed:

• R: Download R
• RStudio (recommended IDE): Download RStudio
• Git: Download Git

Step 1: Clone the Repository

Open Git Bash (or a terminal) in your desired directory, and run:

bash git clone https://github.com/bc3LC/rhap.git

This will create a local copy of the repository.

Step 2: Open the Project in RStudio

• Open the rhap.Rproj file inside the cloned folder using RStudio.
  
• In RStudio, either go to Build Install and Restart (or press Ctrl + Shift + B),
  or load the package manually by running the following code:

r install.packages("devtools") # Skip if already installed devtools::load_all()

Run a Baseline Example (Optional)

The rhap package includes a built-in .dat file that lets you run a test case based on a GCAM baseline scenario. This is a great way to verify that the package is working correctly and to explore its core functionality.

You can run this example with or without cloning the full repository, as the required data is included in the package:

r test_rhap <- rhap::test_rhap

How to guides

Back to Contents

The primary function offered by this package is calc_hap_impacts, designed to estimate health impacts attributable to household air pollution (HAP) across a range of alternative GCAM scenarios. This function estimates scenario-specific health outcomes by seamlessly extracting and processing relevant data from GCAM databases or project files. The extracted data encompasses critical socioeconomic and environmental parameters, enabling comprehensive analysis of HAP impacts. These parameters include per capita GDP, emissions of key pollutants such as primary PM2.5 (BC+OC), NOx, and VOCs, and per capita floorspace metrics. By integrating these diverse factors, calc_hap_impacts facilitates detailed assessments of how variations in economic development, pollutant emissions, and living conditions influence human health under different policy or technological scenarios.

The package also includes an ancillary function, calc_ResidEm_grp, which determines the contribution of each within-region consumer group to household air pollution (HAP), with results categorized by region, year, and pollutant. Users can customize their analysis by specifying the desired region, time period, and pollutant through adjustable parameters when calling the function. This flexibility enables targeted assessments of how various consumer groups influence HAP across specific contexts, providing valuable insights for research and policy development.
