Sweave User Manual
Sweave User Manual Friedrich Leisch and R-core June 30, 2017 1 Introduction Sweave provides a flexible framework for mixing text and R code for automatic document generation. A single source file contains both documentation text and R code, which are then woven into a final document containing • the documentation text together with • the R code and/or • the output of the code (text, graphs) This allows the re-generation of a report if the input data change and documents the code to reproduce the analysis in the same file that contains the report. The R code of the complete 1 analysis is embedded into a LATEX document using the noweb syntax (Ramsey, 1998) which is usually used for literate programming Knuth(1984). Hence, the full power of LATEX (for high- quality typesetting) and R (for data analysis) can be used simultaneously. See Leisch(2002) and references therein for more general thoughts on dynamic report generation and pointers to other systems. Sweave uses a modular concept using different drivers for the actual translations. Obviously different drivers are needed for different text markup languages (LATEX, HTML, . ). Several packages on CRAN provide support for other word processing systems (see Appendix A). 2 Noweb files noweb (Ramsey, 1998) is a simple literate-programming tool which allows combining program source code and the corresponding documentation into a single file. A noweb file is a simple text file which consists of a sequence of code and documentation segments, called chunks: Documentation chunks start with a line that has an at sign (@) as first character, followed by a space or newline character. -

Chapter 1: Introduction to ESS 1 1 Introduction to ESS The S family (S, Splus and R) and SAS statistical analysis packages provide sophisticated statistical and graphical routines for manipulating data. Emacs Speaks Statistics (ESS) is based on the merger of two pre-cursors, S-mode and SAS-mode, which provided support for the S family and SAS respectively. Later on, Stata-mode was also incorporated. ESS provides a common, generic, and useful interface, through emacs, to many statistical packages. It currently supports the S family, SAS, BUGS/JAGS, Stata and XLisp-Stat with the level of support roughly in that order. A bit of notation before we begin. emacs refers to both GNU Emacs by the Free Software Foundation, as well as XEmacs by the XEmacs Project. The emacs major mode ESS[language], where language can take values such as S, SAS, or XLS. -

Nehiba THESIS Submitted to Northern Michigan University In partial fulfillment of the requirements For the degree of MASTER OF SCIENCE Office of Graduate Education and Research July 2018 ABSTRACT By Katie R. Nehiba Current anthropogenically-driven climate change is accelerating at an unprecedented rate. In response, species’ ranges may shift, tracking optimal climatic conditions. Species-specific differences may produce predictable differences in the extent of range shifts. I evaluated if patterns of predicted responses to climate change were strongly related to species’ taxonomic identities and/or ecological characteristics of species’ niches, elevation and precipitation. I evaluated differences in predicted range shifts in well-sampled small mammals that are restricted to North America: kangaroo rats, voles, chipmunks, and ground squirrels. -

First, LATEX has a prominent place in the book. Second, the book describes a very plot(Petal.Length ˜ Petal.Width, interesting offshoot of literate programming, a topic data = iris, xlab = "Petal Width, cm", traditionally popular in the TEX community.

LYX and Knitr
knitr.1 LYX and knitr The knitr package allows one to embed R code within LYX and LATEX documents. When a document is compiled into a PDF, LYX/LATEX connects to R to run the R code and the code/output is automatically put into the PDF. In addition to this being a convenient way to use both LYX/LATEX with R, it also provides an important component to the reproducibility of research (RR). For example, one can include the code for a data analysis de- scribed in a paper. This ensures that there would be no “copying and pasting errors” and also provide readers of the paper an im- mediate way to reproduce the research. RR continues to become more important and fortunately more tools are being developed to make it possible. Below are some discussions on the topic: • AMSTAT News column on RR at http://magazine. amstat.org/blog/2011/01/01/scipolicyjan11. • CRAN task view for RR and R at http://cran.r-project. org/web/views/ReproducibleResearch.html. • Yihui Xie: Author of knitr – First and second editions of his Dynamic Documents with R and knitr book. Note that this book was typed in LYX. – Website for knitr at http://yihui.name/knitr The Sweave environment is another way to include R code inside of LYX/LATEX. This was developed prior to knitr, but it is more difficult to use. The purpose of this section is to examine the main compo- nents of knitr so that you will be able to complete the rest of the semester using LYX and knitr together for all assign- ments in our course! Also, a very important purpose is to give you the tools needed to complete all assignments in other R- based courses by using knitr and LYX together! The files used knitr.2 here are intro_example_cereal.lyx, intro_example_cereal.pdf, cereal.csv, ExternalCode.R, FirstBeamer-knitr.zip, JSM2015.zip, and RMarkdown.zip. -

Introduction
1 Introduction A compiler translates source code to assembler or object code for a target machine. A retargetable compiler has multiple targets. Machine-specific compiler parts are isolated in modules that are easily replaced to target different machines. This book describes lcc, a retargetable compiler for ANSI C; it fo- cuses on the implementation. Most compiler texts survey compiling al- gorithms, which leaves room for only a toy compiler. This book leaves the survey to others. It tours most of a practical compiler for full ANSI C, including code generators for three target machines. It gives only enough compiling theory to explain the methods that it uses. 1.1 Literate Programs This book not only describes the implementation of lcc,itis the imple- mentation. The noweb system for “literate programming” generates both the book and the code for lcc from a single source. This source con- sists of interleaved prose and labelled code fragments. The fragments are written in the order that best suits describing the program, namely the order you see in this book, not the order dictated by the C program- ming language. The program noweave accepts the source and produces the book’s typescript, which includes most of the code and all of the text. The program notangle extracts all of the code, in the proper order for compilation. Fragments contain source code and references to other fragments. Fragment definitions are preceded by their labels in angle brackets. For example, the code ≡ a fragment label 1 ĭ2 sum=0; for (i = 0; i < 10; i++) increment sum 1 increment sum 1≡ 1 sum += x[i]; sums the elements of x. -

Literate Programming and Reproducible Research
JSS Journal of Statistical Software January 2012, Volume 46, Issue 3. http://www.jstatsoft.org/ A Multi-Language Computing Environment for Literate Programming and Reproducible Research Eric Schulte Dan Davison University of New Mexico Counsyl Thomas Dye Carsten Dominik University of Hawai`i University of Amsterdam Abstract We present a new computing environment for authoring mixed natural and com- puter language documents. In this environment a single hierarchically-organized plain text source file may contain a variety of elements such as code in arbitrary program- ming languages, raw data, links to external resources, project management data, working notes, and text for publication. Code fragments may be executed in situ with graphical, numerical and textual output captured or linked in the file. Export to LATEX, HTML, LATEX beamer, DocBook and other formats permits working reports, presentations and manuscripts for publication to be generated from the file. In addition, functioning pure code files can be automatically extracted from the file. This environment is implemented as an extension to the Emacs text editor and provides a rich set of features for authoring both prose and code, as well as sophisticated project management capabilities. Keywords: literate programming, reproducible research, compendium, WEB, Emacs. 1. Introduction There are a variety of settings in which it is desirable to mix prose, code, data, and compu- tational results in a single document. Scientific research increasingly involves the use of computational tools.
