The simplest way to use sen2r is to execute it in interactive mode. These commands will open the GUI provided with by function
Note that the following error message could be returned:
Some missing packages are needed to run the GUI; please install them with the command > install.packages("leaflet", "leafpm", "mapedit", "shiny", "shinyFiles", "shinydashboard", "shinyjs", "shinyWidgets")

The left-side bar of the dashboard allows instead to:
sen2r()execution will start (the user will be able to monitor
sen2r()progress from the processing messages sent to R console or to a log file, if this option was chosen with the previous button);
