任何练习/测试/考试都可以免费获得答案来测试基本的R知识

时间：2021-10-10 01:59:07

I have the responsibility of ensuring that a colleague who is just learning R knows the basics before a course where that is a requirement. The colleague has gone through a couple of tutorials so hopefully she is ok, but I would like to give her a test to gauge it.

我有责任确保刚学习R的同事在课程开始之前就知道这是一个要求。我的同事已经通过了几本教程，希望她还可以，但是我想给她一个测试来测试一下。

I was therefore wondering if anyone knew if there were any materials on the web that would be suitable? and is possible had both questions and answers.

因此我想知道是否有人知道网络上是否有合适的资料?有问题也有答案。

There is a whole set of exercises with solutions from the book Data Analysis and Graphics Using R. (Maindonald & Braun, 2nd edn, CUP 2007) available online : http://maths.anu.edu.au/~johnm/r-book/2edn/exercises/

Next to that, a quick search using the obscure randomized pagecollector Google brought to me a set of exercises where you can pick out whatever you want. Try the magic phrase "R exercises". ;)

If this is just a one time single person evaluation then a oral style exam is probably going to tell you a lot more than a set of fixed problems. Get a data set and have her read it into R, do some basic data manipulation, a couple of plots, and a standard analysis or two. Based on what she does well or has a challenge with you can modify the direction that you have things go and what additional questions you ask.

如果这只是一次单独的个人评估那么口语考试可能会告诉你比一组固定的问题多得多的东西。获取一个数据集，让她把它读到R中，做一些基本的数据操作，一些图表，以及一两个标准的分析。基于她做得好或有挑战，你可以改变你的方向，你问的其他问题。
