svyLocAdj

svyLocAdj is an R package for adjusting and analyzing Demographic and Health Survey (DHS) data using Bayesian modeling approaches implemented through Stan.

Prerequisites

Before installing svyLocAdj, users must ensure that:

1. A working C++ compiler/toolchain is installed.
2. The rstan package is successfully installed and configured.

Since svyLocAdj uses Stan for Bayesian computation, proper compiler and rstan installation are required.

Step 1: Verify Compiler Installation

Windows

Install Rtools corresponding to your version of R:

https://cran.r-project.org/bin/windows/Rtools/

After installation, verify that the compiler is available:

install.packages("pkgbuild")
pkgbuild::has_build_tools(debug = TRUE)

A return value of TRUE indicates that the build tools are correctly configured.

macOS

Install Apple’s Command Line Tools:

xcode-select --install

Linux

For Ubuntu/Debian systems:

sudo apt update
sudo apt install build-essential

For other Linux distributions, install the equivalent GNU compiler tools.

Step 2: Install RStan

Install rstan and its dependencies:

install.packages(c("StanHeaders", "rstan"), dependencies = TRUE)

Load rstan and verify that it is working correctly:

library(rstan)

rstan_options(auto_write = TRUE)
options(mc.cores = parallel::detectCores())

For detailed installation instructions and platform-specific guidance, see:

https://mc-stan.org/users/interfaces/rstan

Step 3: Install devtools

If devtools is not already installed:

install.packages("devtools")

Step 4: Install svyLocAdj from GitHub

Install the latest development version from GitHub:

devtools::install_github("ksbakar/svyLocAdj")

Replace USERNAME with the GitHub username or organization hosting the repository.

Step 5: Load the Package

library(svyLocAdj)

Confirm the installation:

packageVersion("svyLocAdj")

Troubleshooting

Stan Model Compilation Errors

If Stan models fail to compile:

1. Verify that the compiler toolchain is installed correctly.
2. Restart R after installing Rtools (Windows) or Command Line Tools (macOS).
3. Reinstall or update rstan and StanHeaders:

install.packages(c("StanHeaders", "rstan"))

4. Check compiler availability:

pkgbuild::has_build_tools(debug = TRUE)

Windows-Specific Issues

Ensure that:

• The correct version of Rtools is installed.
• Rtools is available on the system PATH.
• Your R version is compatible with the installed Rtools version.
