My suggestion is to incorporate the information in the lesson that we can integrate Unix shell with R. For example; we can use R software on the terminal (Unix environment) by using R scripts as we do in a separate R studio. And if we again want to switch to a Unix shell environment then we will simply write EXIT in the terminal and we will again come to the Unix environment.
