Switch to another environment's R — pixi

Move your work to the R of another of the project's environments, e.g. one with another version of R. A running R can't change its own version or library, so this starts the other R the way your IDE needs:

RStudio: starts a new RStudio with the environment's R, in the project. Close the old one when you're done with it.
Positron: looks for interpreters again, and opens the interpreter picker, to pick the environment's R.
VS Code, and editors based on it: points the R extension at the environment's R, in the project's .vscode/settings.json, keeping its console (R, arf or radian; see use_pixi_vscode()). Reload the window to use it. On Windows, start the editor from the environment instead.
Emacs, Neovim and Zed: points the project's .envrc at the environment (see use_pixi_direnv()). Reload direnv in the editor, and restart R. On Windows, start the editor from the environment instead.
Elsewhere: shows the command that starts the environment's R.

The environment is installed first, if it isn't yet.

Usage

pixi_switch(environment = NULL, ide = NULL, path = NULL)

Value

The environment's R, invisibly, or NULL if you cancel the menu.
