define_exercises_from_csv: Define exercises from a csv file

In rexer: Random Exercises and Exams Generator

Define exercises from a csv file

Description

Each row in the text file is interpreted as an exercise. We only need to define the columns that we are going to use; the rest of the columns are taken by default.

Usage

define_exercises_from_csv(ex, file, sep)

## S3 method for class 'exam'
define_exercises_from_csv(ex, file, sep = ",")

Arguments

ex	An 'exam' object.
file	A string, name of a text file.
sep	Column separator character ("," or ";").

Details

Both the answer and the options are formed by a vector of strings, from which one is chosen to formulate the exercise and select the answer. To represent a vector of strings in a cell, the function 'vector_to_string()' is used, which includes a separator ("<|>") between the vector elements to generate a string.

Value

An 'exam'.
