1. Download and run the CRAN installer for Windows
2. Install Rtools (required for packages that compile native code)
   • Choose the Rtools version that matches your R release.
   • Make sure that R is added to your system path.

Verify installation:

R --version
Rscript -e "install.packages('jsonlite', repos='https://cloud.r-project.org'); cat('ok\n')"

If R is not found, R is most likely missing in your system variables. Open environmental variables and add the path to your R executable. R is most likely install at C:\Program Files\R\R-VERSION\bin\x64.

1. Download and run the CRAN package for macOS
   • Alternatively install via Homebrew: brew install --cask r and optionally brew install r

2. Install Xcode command line tools for compilers:

   xcode-select --install
   

Verify installation:

R --version
Rscript -e "install.packages('jsonlite', repos='https://cloud.r-project.org'); cat('ok\n')"

1. Install R from the distribution repositories or CRAN (CRAN often provides newer versions). Example (Debian/Ubuntu):

   sudo apt-get update
   sudo apt-get install r-base r-base-dev
   

2. Install build tools and Fortran for compiling packages:

   sudo apt-get install build-essential gfortran libblas-dev liblapack-dev
   

Verify installation:

R --version
Rscript -e "install.packages('jsonlite', repos='https://cloud.r-project.org'); cat('ok\n')"
