This function will launch the interactive learning environment.

learn(assign.env = parent.frame(1))



An environment


This function initializes the interactive environment by proposing to select a CSV file from the directory inst/extdata/. Once the file is selected, the function reads the selected dataset and adds a numeric variable, named Score, if not already existing. It also replaces any existing missing values by 0 from the Score variable. Finally the function returns to the sessionQuestions function, or to the sessionExit function if 0 is typed.


In order to study a new CSV file, simply save it into the inst/extdata/ directory.

If you have any problem with the encoding, or if you want to read a dataset with an non-Latin alphabet, please type ?Sys.setlocale() and follow the instructions.
