RPackagesOffline

RPackagesOffline is a repository providing a collection of R package files for offline installation. It allows R users to install packages on systems with no internet access by using pre-downloaded package archives. This is especially useful in secure environments or remote locations where CRAN access is unavailable.

Repository Purpose

• Offline R Packages: Contains R package binaries (e.g., .zip for Windows ) stored in the packages/ folder. These can be installed without an internet connection.
• Use Cases: Ideal for installing R packages on servers or computers that are offline or behind firewalls, by transferring these files via USB or internal network share.
• Dependencies: The repository aims to include not just the main packages but also their key dependencies.

Prerequisites

• R Installation: You need R installed on the target offline system. Make sure the R version is compatible with the package files:
  • For Windows .zip packages, use the corresponding R version (the binary packages are often specific to a major R release, e.g., packages built for R 3.x won’t work on R 4.x, and vice versa).
• Disk Space: Sufficient space to store and install the packages.
• No Internet Required: All installations from this repository are done offline.

2. Modify file DownloadRPackages.ps1, with the R packages you would like to download.
3. Run .\DownloadRPackages.ps1 from the folder, Script will create a subfolder "Packages" and download the packages and dependant packages.
4. Transfer to Offline Machine: Copy the packages/ folder and LoadRPackages.ps1 to the offline system via USB, network share, etc.
5. Run .\LoadRPackages.ps1 on the offline system that already has R installed.
