Computing for Data Analysis（Johns Hopkins University）

• How is this course different from “Data Analysis”?
  This course will focus on developing the programming skills necessary for managing data and for implementing statistical methods. The course will not focus on teaching properties of specific statistical algorithms unless they are used to demonstrate important programming techniques. Some of the topics covered in this course are relevant to the “Data Analysis” course but the two do not need to be taken in sequence.
  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.
  感觉蛮实用的，而且只用4周，不会占用太多时间，有没有筒子一起学习
  
  

我今天刚开始

恩，刚开始，学习下R

我也是，主要想看看R的绘图功能

正在听.....感觉废话略多.....不知道是不是刚开始的原因.......先听听看

我第一周的题目做完了，得了八分。

我也打算上这门课，有人一起学太好了。。这周末开始听课+写作业。。

刚刚写完Week1的作业第一个quiz十道选择题，第一次错了一道...再试一次发现有题目和第一次不一样的
第二个programming assignment比较简单，但R的一些语法不太熟，十道题花了40分钟才搞掂

和楼上一样，Quiz 1 第一次做错了一道题。原来语句 “1:100” 产生的是整型啊！
