[Coursera] Computing for Data Analysis (Week #1)

老师：Professor Roger D. Peng

课程简介：
This course is about learning the fundamental computing skills necessary for effective data analysis. You will learn to program in R and to use R for reading data, writing functions, making informative graphs, and applying modern statistical methods.

作业：
Quizzes:
There will be four weekly quizzes that will test your comprehension of the material covered in the lecture material provided that week. The quizzes will consist of multiple choice, true/false, or short answer questions. Each quiz is worth 10 points. You will be allowed 3 attempts to submit each quiz and your maximum score will be taken as the final score.
Programming Assignments:
There will be four programming assignments that will involve writing R code and R functions. These assignments will allow you to work on your R programming skills and practice writing and debugging code. For each programming assignment you will be asked to write R code or functions that produce output given a certain input. Your grade on the assignment will be based on whether the output your function produces matches the correct output. Details can be found in the descriptions of each programming assignment.

第一周的内容：

• Introduction and overview
• Installing R
• Data types, subsetting
• Reading/writing data
  

第一次发公开课贴啊，其实第三周的内容已经出来了，有点略晚= =b
课程一共四周，算是R的入门，感觉为另一门课Data Analysis铺垫的。
时间比较短，老师也是介绍一下各方面的知识，主要通过作业来巩固，论坛讨论比较热烈，能够学到不少东东，不管是数据分析或者学术论文画图都挺有用的。

第一次Quiz和Programming Assignment都是通过选择题的方式，图就不截了吧。
