R introduction

This introduction to R is derived from an original set of notes describing the S and S-Plus environments written in 1990-2 by Bill Venables and David M. Smith when at the University of Adelaide. We have made a number of small changes to reflect differences between the R and S programs, and expanded some of the material We offer here a couple of introductory tutorials on basic R concepts. It serves as background material for our main tutorial series Elementary Statistics with R. The only hardware requirement for most of the R tutorials is a PC with the latest free open source R software installed R is a popular programming language used for statistical computing and graphical presentation. Its most common use is to analyze and visualize data

  3. Because it's a programmable environment that uses command-line scripting, you can store a series of complex data-analysis steps in R. That lets you re-use your analysis work on similar data more..
  4. 1 Introduction R is a powerful language and environment for sta-tistical computing and graphics. It is a public do-main (a so called \GNU) project which is similar to the commercial S language and environment which was developed at Bell Laboratories (for-merly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered a
  5. R control structures are blocks of code that allows you to modify the control flow of your code. You can create conditions or repeat or cycle some blocks of code depending on some events. These control structures include the if else statement, the for loop (and how to optimize its performance) and the while loop
  6. R is a command line driven program. The user enters commands at the prompt (> by default) and each command is executed one at a time

R is an expression language with a very simple syntax It is case sensitive, so A and a are different symbols and would refer to different variables All alphanumeric symbols are allowed as variable names plus '.' and '_ R script (1) The usual Rstudio screen has four windows: 1. Console. 2. Workspace and history. 3. Files, plots, packages and help. 4. The R script(s) and data view. The R script is where you keep a record of your work. For Stata users this would be like the do-file, for SPSS users is like the syntax and for SAS users the SAS program. 9 DSS/OT In Introduction to R, you will master the basics of this widely used open source language, including factors, lists, and data frames. With the knowledge gained in this course, you will be ready to undertake your first very own data analysis. Oracle estimated over 2 million R users worldwide in 2012, cementing R as a leading programming language in statistics and data science. Every year, the number of R users grows by about 40%, and an increasing number of organizations are using it in their.
