xopen

xopen is a cross-platform R package that opens files, directories, or URLs using their associated system applications. It works consistently across Windows, macOS, and Linux, similar to R’s shell.exec() but with better platform support.

The package handles platform differences automatically, removing the need to write OS-specific code for opening external resources. You can open items with their default applications or specify a particular application to use. It also supports passing command-line arguments to applications, making it useful for launching programs with specific configurations or parameters.
