answer_check: Check answers of multiple choice questions

Description

Check answers of multiple choice questions by matching the answers with the correct sequence.

Usage

answer_check(dat, seq, multi_column = FALSE)

Value

A data frame of boolean values, with ncol equals the number of questions.

Arguments

dat

A data frame of answers.

seq

A vector of correct answers, one element for each question.

multi_column

Logical, whether the multi-answers are in multiple columns.

Details

If multi_column is TRUE, the answers for Multiple-Answer Questions should be in multiple columns of logicals, with each column representing a choice. The seq should be a string of "T" and "F". If multi_column is FALSE, the answers for Multiple-Answer Questions should be in one column, and the function would expect an exact match of seq.

Examples

dat <- data.frame(Q1 = c("A", "B", "C"), Q2 = c("AD", "AE", "ABF"))
seq <- c("A", "AE")
answer_check(dat, seq)
dat <- data.frame(
  Q1 = c("A", "B", "C"), Q2.A = c(TRUE, TRUE, FALSE),
  Q2.B = c(TRUE, FALSE, TRUE), Q2.C = c(FALSE, TRUE, FALSE)
)
seq <- c("A", "TFT")
answer_check(dat, seq, multi_column = TRUE)
