Statistical Computing and S Scene-setting: Statistical Computing 1980 Mainly Fortran programming, or PL/I (SAS). Batch computing (SAS, BMDP, SPSS, Genstat) with restricted range of platforms. Some small interactive systems (GLIM 3.77, Minitab). Very poor interactive graphics (2400 baud to a Tektronix storage tube if you were lucky). Flatbed and drum plotters, microﬁlm for publication-quality output off-line. Mainly home-brew solutions in research. (GLIM macros?) 1990 PCs become widespread, but FPUs still uncommon. Sun etc workstations available for researchers, and for teaching in a few places. Graphics could be pretty good (postscript printers, ca 1000 × 1000 pixel screens), but often was not, and mono text terminals were still widespread. C was beginning to be used, as more portable than Fortran. (Few PC Fortran compilers then and now.) Still SAS, SPSS etc as batch programs. S beginning to be make an impact on research and teaching. 2001 Little spread in machine speed (min 500MHz, max 1.5GHz), fast FPUs are universal. Colour everywhere, usually 24-bit colour. The video-games generation is now at university.

It’s just crazy.” Wickham earned his renown as the preeminent developer of packages for R, a programming language developed for data analysis. Packages are programming tools that simplify the code necessary to complete common tasks such as aggregating and plotting data. He has helped millions of people become more efficient at their jobs -- something for which they are often grateful, and sometimes rapturous. The packages he has developed are used by tech behemoths like Google, Facebook and Twitter, journalism heavyweights like the New York Times and FiveThirtyEight, and government agencies like the Food and Drug Administration (FDA) and Drug Enforcement Administration (DEA). Truly, he is a giant among data nerds. *** Born in Hamilton, New Zealand, statistics is the Wickham family business: His father, Brian Wickham, did his PhD in the statistics heavy discipline of Animal Breeding at Cornell University and his sister has a PhD in Statistics from UC Berkeley.

I R provides an enviroment in which you can perform statistical analysis and produce graphics. The R History I R is based on the computer language S, developed by John Chambers and others at Bell Laboratories in 1976. I In 1993 Robert Gentleman and Ross Ihaka at University of Auckland wanted to experiment with the langauge, so they developed an implementation, and named it R. I They made it open source in 1995. Its users are free to see how it is written and thousands of people around the world have contributed to its development. Design of the R System I The primary R system is available from the Comprehensive R Archive Network (CRAN) which hosts many add-on packages that can be used to extend the functionality of R. The R system is divided into 2 conceptual parts: I The ‘base’ R system that you download from CRAN: It contains the base package which is required to run R and contains the most fundamental functions. Other basic packages such as as stats, graphics, grid, cluster, et al. are included.

Introducing R Online Version At
Introducing R Online Version at https://data.princeton.edu/R Germán Rodríguez Princeton University Updated November 2020 The purpose of these notes is to provide a quick introduction to R, particularly as a tool for fitting linear and generalized linear models. The notes originated in a 1992 handout introducing S-Plus, but have been substantially rewritten to target R using R Studio. Each of the subjects discussed here includes a sample application. Additional examples will be found in the R logs of my GML course, as well as in the pages for courses on Multilevel Models, Survival Analysis and Demographic Methods, all at https://data.princeton.edu. 1 Introduction R is a powerful environment for statistical computing which runs on several platforms. These notes are written specially for users running the Windows version, but most of the material applies to the Mac and Linux versions as well. 1.1 The R Language and environment R was first written as a research project by Ross Ihaka and Robert Gentleman, and is now under active development by a group of statisticians called ‘the R core team’, with a home page at https://www.r-project.org. R was designed to be ‘not unlike’ the S language developed by John Chambers and others at Bell Labs. A commercial version of S with additional features was developed and marketed as S-Plus by Statistical Sciences, eventually becoming part of TIBCO Spotfire. You can view R and S-Plus as alternative implementations of the same underlying S language. The modern R implementation, however, is by far the most popular.
