The Statistical Programming Language". Your name.
Close Send. Then drag the Beginning. RData file into that directory and use the load command:. R uses named objects so everything gets a name. You can see what is included in the Beginning. RData file by using the ls command:. This will show you everything currently in the memory of R. Remember that names are case sensitive so that Qty is not the same as qty. There are four main kinds of object in the Beginning.
RData file:. Many of the objects in the Beginning. RData file are data. For example the bv object shows some results for visits of bees to various colors of flower. These data are used to carry out a Goodness of fit test by comparing the observed visits to the theoretical ratio expected. Some of the objects in the Beginning. RData file are results. For example the pw. R is very flexible and one useful aspect is the ability to create simple functions.
For example the pn object is a function that applies a polynomial formula to any numerical value. In this case the polynomial formula was taken from a previous analysis and is used to draw a line of best-fit onto a graph.
If you require a more complex task or want to automate your workflow, you can create a longer "script". The cum. This script allows you to generate a cumulative statistic for a set of numbers. The default uses the median but you can specify any sensible function the mean for example to create a running mean.
Instructors teachers, lecturers, professors can now access a range of support materials via the Instructor Companion Site on the Wiley Higher Education website you have to register but it is free. If you are an instructor and are teaching R then these materials can help you structure your course and provide you with additional materials that you can press into service as you like.
Mark Gardener. Data Analysis.
The Statistical Programming Language by: Beginning R: Mark Gardener Conquer the complexities of this open source statistical language R i s fast becoming the de facto standard for statistical computing and analysis in science, business, engineering, and related fields.
R, the open source statistical language increasingly used to handle statistics and produces publication—quality graphs, is notoriously complex This book makes R easier to understand through the use of simple statistical examples, teaching the necessary elements in the context in which R is actually used Covers getting started with R and using it for simple summary statistics, hypothesis testing, and graphs Shows how to use R for formula notation, complex statistics, manipulating data, extracting components, and regression Provides beginning programming instruction for those who want to write their own scripts Beginning R offers anyone who needs to perform statistical analysis the information necessary to use R with confidence.
The following outline covers each chapter of the book. RData file for the example data used in the book Back to top. What It Is and How to Get It What you will learn in this chapter Discovering what R is Getting to the R program Installing it on your computer Starting to run the program Using the help system and finding help from other sources Obtaining additional libraries of commands In this chapter you see how to get R and install it on your computer.
Becoming Familiar With R What you will learn in this chapter How to use R for simple math How to store results of calculations for future use How to create data objects from the keyboard, clipboard, or external data files How to see the objects that are ready for use How to look at the different types of data objects How to make different types of data objects How to save your work How to use previous commands in the history This chapter builds some familiarity with working with R, beginning with some simple math and culminating in importing and making data objects that you can work with and saving data to disk for later use.
Working With Objects What you will learn in this chapter How to manipulate data objects How to select and display parts of data objects How to sort and rearrange data objects How to construct data objects How to determine what form a data object is How to convert a data object from one form to another This chapter deals with manipulating the data that you have created or imported. Descriptive Statistics and Tabulation What you will learn in this chapter How to summarize data samples How to use cumulative statistics How to create summary tables How to cross-tabulate How to test for different object types This chapter is all about summarizing data.
Distribution What you will learn in this chapter How to create histograms and other graphics of sample distribution How to examine various distributions How to test for the normal distribution How to generate random numbers In this chapter you look at visualizing data using graphical methods—for example, histograms—as well as mathematical ones.
Example data file The book includes many examples and these are included in the Beginning. Get the example data You can download that file by clicking on the link. Install the example data Once you have the file on your computer you can load it into R by one of several methods: For Windows or Mac you can drag the Beginning. RData file icon onto the R program icon; this will open R if it is not already running and load the data. If R is already open, the data will be appended to anything you already have in R otherwise only the data in the file will be loaded.
If you have Windows or Macintosh you can load the file using menu commands or use a command typed into R: Alternatively you can find the working directory in R by using the getwd command: RData file into that directory and use the load command: RData" Using the example data R uses named objects so everything gets a name.
RData file by using the ls command: RData file: Data Many of the objects in the Beginning. Instructor support materials available via Wiley Back to top. Instructor Support Materials Instructors teachers, lecturers, professors can now access a range of support materials via the Instructor Companion Site on the Wiley Higher Education website you have to register but it is free. The materials include: An annotated syllabus split into 30 sections. Intended to be approximately 1 hour each section.
A series of PowerPoint decks.
Each deck is linked to a section of the annotated syllabus. Classroom exercises. These compliment the 30 sections of the syllabus and form a structured approach to teaching R. Questions and Answers. Each of the 12 chapters has 12 questions the answers are separate. The questions are in 3 forms:
