learn: Initialize the interactive environment

In polyglot: Learn Foreign Language Vocabulary

Description

This function will launch the interactive learning environment.

Usage

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

Arguments

assign.env

An environment

Details

This function initializes the interactive environment by proposing to select a CSV file from the caching directory built with the pins package. 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.

Note

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.

Examples

if(interactive()){
learn()
}
