Compile R script into standalone .exe file?

Compile R script into standalone .exe file?

Creating a standalone executable file (.exe) from an R script allows you to run the R script without the need for an R installation on the target system. This can be useful for distributing R-based applications to users who may not have R installed.

To create a standalone .exe file from an R script, you can use a combination of tools that package the R runtime along with your script and any required packages. One popular method is to use the Rscript command and bundle it into a standalone executable using tools like RInno or Rshiny standalone.

However, the most commonly used tool for converting R scripts into standalone executables is RInno, which allows you to create an installer for your R application. Below are the steps to accomplish this:

Step 1: Install R and RTools

Ensure that you have R and RTools installed on your system. If you don't, download them from CRAN and RTools.

Step 2: Install RInno

Install the RInno package in R:

install.packages("RInno")

Step 3: Create an Installer Project

RInno creates a project structure for building installers. The following example demonstrates how to create a new installer project:

library(RInno) # Create a new Inno Setup project create_app( app_name = "MyRApp", # Name of your application app_dir = "path/to/your/RScriptDir", # Path to your R script run_now = FALSE # Set to TRUE if you want to run the installer immediately )

This creates a folder structure with configuration files needed to build the installer.

Step 4: Configure and Build the Installer

After creating the project, configure it to ensure your script and required packages are included:

# Include additional R packages config_app( app_name = "MyRApp", packages = c("ggplot2", "dplyr"), # List any required R packages app_version = "1.0.0" ) # Build the Inno Setup installer build_installer( app_name = "MyRApp" )

This step creates an installer using Inno Setup. If you don't have Inno Setup installed, RInno will guide you through the installation process.

Step 5: Distribute the Installer

After building the installer, you can distribute it as a standalone executable file. Users can install your R-based application without requiring a separate R installation.

Limitations

  • While this approach creates an executable installer, it doesn't produce a single standalone .exe file; it creates an installer package containing the necessary files.
  • The target system will have a basic R runtime environment installed with your script and required packages.
  • This process is mainly designed for Windows systems; it might not work as intended on macOS or Linux.

If you need to create a single executable without requiring an R installation, consider using more complex approaches like converting the R script to another language or integrating with C/C++ and then compiling to an executable. These methods often require additional expertise and resources.
