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 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.
