The Assignments and quizzes are quite good, and illustrates the lessons very well. A very useful course. The audio quality of some lectures especially those by the main instructor was not good. This course completes the sister course of R programming and they work together. In this first week of the course, we look at finding data and reading different file types.
Downloading Files. Getting and Cleaning Data. Enroll for Free. This Course Video Transcript. From the lesson Week 1 In this first week of the course, we look at finding data and reading different file types. Obtaining Data Motivation And if [43] starts a line, then that would mean the first number on that line would represent the 43rd entry in the vector. R has some powerful functions for making graphics. We can create a simple plot. Before we review the code for this plot, let's summarize the trends we see in the.
Which of the following best describes the number of girls baptised over the years included in this dataset? After there is a decrease in the number of girls baptised, but the number begins to increase again in Overall the trend is an increase in the number of girls baptised. This number peaks around and then after the number of girls baptised decreases. Back to the code If you run the. Notice that the command above again looks like.
Thankfully, R documents all of its functions extensively. To read what a function. Try the following in. Notice that the help file replaces the plot in the lower right panel. The best and easiest way to learn the syntax is. R as a big calculator. Now, suppose we want to plot the total number of baptisms. To compute this, we.
We can type in. We could repeat this once for each. If we add the vector for baptisms for boys to. Take a. Adding a new variable to the data frame. We'll be using this new vector to generate some plots, so we'll want to save it.
What in the world is going on here? Basically, it takes the output of the current line and pipes it into. Then assign this new resulting dataset to the object.
This is essentially equivalent to going through each row and adding up the boys. We can make a plot of the total number of baptisms per year with the following command.
You want both? Just layer them on:. Finally, in addition to simple mathematical operators like subtraction and. For example, we can ask if boys outnumber girls in each. This variable contains different kind of. In general, data analysis will involve many different kinds of data. Dataset 2: Present birth records. In the previous few pages, you recreated some of the displays and preliminary. Next you will do a similar analysis,.
Load up the. Calculate the total number of births for each year and store these values in a new. Then, calculate the proportion of.
Plot these values over time and based on the plot determine if the. Based on this. Plot these values over time.
