f_open_file: Open a File with the Default Application

In rfriend: Provides Batch Functions and Visualisation for Basic Statistical Procedures

Open a File with the Default Application

Description

Opens a specified file using the default application associated with its file type. It automatically detects the operating system (Windows, Linux, or macOS) and uses the appropriate command to open the file.

Usage

f_open_file(filepath)

Arguments

filepath

A character string specifying the path to the file to be opened. The path can be absolute or relative.

Details

- On Windows, the f_open_file() function uses shell.exec() to open the file. - On Linux, it uses xdg-open via the system() function. - On macOS, it uses open via the system() function.

If an unsupported operating system is detected, the function will throw a message.

Value

Does not return a value; it is called for its side effect of opening a file.

# NOTE: The use of "if(interactive())" prevents this example from running
# during automated CRAN checks. This is necessary because the example
# opens a file, a behavior restricted by CRAN policies for automated
# testing.You don't need to use "if(interactive())" in your own scripts.
