Conclusión

Asi como Jingle Bells, pueden existir muchas otras canciones que pueden ser codificadas en R, primero se establecen las teclas como sonidos, para asi despues asignarle una duración a cada tecla. Rmusic::play_music en este caso sirve para reproducir la canción con las teclas y duración establecidas, y Rmusic::save_music sirve para guardarlo en tu carpeta.

Nuevamente podemos observar que RStudio puede manejar una cantidad inmensa de paquetes y librerias que ayudan a ejecutar cualquier idea que el usuario tiene en mente.
