Facing issues in setting up environment for data science (R, Python)

Hi,
Was trying to setup Data Science environment in idx but couldn’t . Seems like idx can’t find rPackages. Any workaround?

Here’s my dev.nix config for reference :

# dev.nix configuration with correct R package
{ pkgs, ... }: {
  channel = "stable-24.05"; # Choose the appropriate nixpkgs channel
  packages = [
    pkgs.rPackages.tidyverse        # Equivalent to using rocker/tidyverse in Dockerfile
    pkgs.rPackages.iRkernel         # Jupyter kernel for R
    pkgs.python311Packages.jupyterlab                 # JupyterLab environment
    pkgs.rPackages.quarto                 # Quarto CLI for literate programming and markdown
    pkgs.python311                  # Python3 for JupyterLab, etc.
    pkgs.python311Packages.pip      # Python package installer
    pkgs.rstudio
    pkgs.rstudio-server
  ];
  
  # Set environment variables for the workspace
  env = {
    RSTUDIO_PORT = "8787";
    JUPYTER_PORT = "8888";
  };

  idx = {
    extensions = [
      # Equivalent VS Code extensions from open-vsx
      "REditorSupport.r"
      "ms-toolsai.jupyter"
      "ms-python.python"
      "ms-python.vscode-pylance"
      "GitHub.copilot"
      "vsls-contrib.codetour"
    ];

    # Workspace lifecycle hooks
    workspace = {
      # Runs when a workspace is first created
      onCreate = {
        # Install any Python dependencies mentioned in the requirements.txt file
        install-deps = "pip install --user -r requirements.txt";
        # Default open files like the dev.nix and README.md files
        default.openFiles = [ ".idx/dev.nix" "README.md" ];
      };

      # Runs when the workspace is (re)started
      onStart = {
        # Start RStudio Server when the workspace starts
        start-rstudio = "rstudio-server start";
        # Start JupyterLab without authentication
        start-jupyter = ''
          jupyter lab \
          --ServerApp.ip="0.0.0.0" \
          --ServerApp.allow_origin="*" \
          --ServerApp.port=8888 \
          --ServerApp.token="" \
          --ServerApp.password="" \
          --no-browser &
        '';
      };
    };
  };
}

Hey did you mean to specify IRkernel instead of iRkernel?

My bad, sorry for the typo

environment.systemPackages = [
    pkgs.rPackages.IRkernel
  ];
