true-false 考试 R 包中的问题

Question

我正在尝试在考试 R 包中构建一个 true-false 问题。这是一个单选练习，答案列表中只有两个可能的答案。这是代码：

Question
========
¿Puede una variable clasificarse como cualitativa continua?

Answerlist
----------
* Si
* No

Solution
========
No es posible ya que una variable continua debe ser nesezariamente una variable cuantitativa.

Answerlist
----------
* False
* True

Meta-information
================
exname: Escalas de medicion 01
extype: schoice
exsolution: 01
exshuffle: 2

运行 exams2html(question.Rmd) 后输出有三个可能的答案，包括 NA

我做错了什么？

这是 exams 包中的错误，仅在特定情况下才会发生。它已在包的 2.4-0 版（当前开发版本）中得到修复。您可以通过以下方式安装它：

install.packages("exams", repos = "http://R-Forge.R-project.org")
