Tutorial: Emacs Speaks Statistics Richard M. Heiberger1;? , Martin Maechler2 1. Temple University, Philadelphia, PA 2. ETH Zurich ?Contact author: [email protected] Keywords: ESS, R, development environment Abstract This tutorial will introduce the emacs environment, ESS (Emacs Speaks Statistics), for editing R code and interacting with R. Emacs Speaks Statistics (ESS) is an add-on package for emacs text editors. It is designed to support editing of scripts and interaction with various statistical analysis programs such as R, S-Plus, SAS, Stata and JAGS. Although all users of these statistical analysis programs are welcome to apply ESS, advanced users or professionals who regularly work with text-based statistical analysis scripts, with various statistical lan- guages/programs, or with different operating systems might beneﬁt from it the most. Goals Show new users the advantages of using ESS and emacs. Show existing users newly-developed tools, such as those for literate programming (both Sweave and Org-babel). Outline 1. Introduction (5 minutes) 4. Emacs extensions, including Sweave and Org-babel (40 minutes) 2. Using Emacs (45 minutes) Exercise 2: Sweave 3. Using ESS (60 minutes) 5. Emacs Lisp and customization (20 minutes) Exercise 1: ESS 6. Future directions for ESS, wrap-up (10 minutes) Prerequisites Attendees should have a working knowledge of R. Some previous experience with Emacs is helpful, but not essential. Bring your laptop with you to complete the exercises. Please install R on it, and if possible, Emacs and ESS. Precompiled Emacs+ ESS bundles for Windows and Mac are available on the ESS home page http://ess.r-project.org/. Intended Audience We hope to attract both new users and provide a base for existing users to swap ideas and discuss future plans for ESS.

Emacs Speaks Statistics (ESS): a Multi-Platform, Multi-Package Intelligent Environment for Statistical Analysis
Emacs Speaks Statistics (ESS): A multi-platform, multi-package intelligent environment for statistical analysis A.J. Rossini Richard M. Heiberger Rodney A. Sparapani Martin Machler¨ Kurt Hornik ∗ Date: 2003/10/22 17:34:04 Revision: 1.255 Abstract Computer programming is an important component of statistics research and data analysis. This skill is necessary for using sophisticated statistical packages as well as for writing custom software for data analysis. Emacs Speaks Statistics (ESS) provides an intelligent and consistent interface between the user and software. ESS interfaces with SAS, S-PLUS, R, and other statistics packages under the Unix, Microsoft Windows, and Apple Mac operating systems. ESS extends the Emacs text editor and uses its many features to streamline the creation and use of statistical software. ESS understands the syntax for each data analysis language it works with and provides consistent display and editing features across packages. ESS assists in the interactive or batch execution by the statistics packages of statements written in their languages. Some statistics packages can be run as a subprocess of Emacs, allowing the user to work directly from the editor and thereby retain a consistent and constant look- and-feel. We discuss how ESS works and how it increases statistical programming efﬁciency. Keywords: Data Analysis, Programming, S, SAS, S-PLUS, R, XLISPSTAT,STATA, BUGS, Open Source Software, Cross-platform User Interface. ∗A.J.

An Introduction to ESS + Xemacs for Windows Users of R
An Introduction to ESS + XEmacs for Windows Users of R John Fox∗ McMaster University Revised: 23 January 2005 1WhyUseESS+XEmacs? Emacs is a powerful and widely used programmer’s editor. One of the principal attractions of Emacs is its programmability: Emacs can be adapted to provide customized support for program- ming languages, including such features as delimiter (e.g., parenthesis) matching, syntax highlight- ing, debugging, and version control. The ESS (“Emacs Speaks Statistics”) package provides such customization for several common statistical computing packages and programming environments, including the S family of languages (R and various versions of S-PLUS), SAS, and Stata, among others. The current document introduces the use of ESS with R running under Microsoft Windows. For some Unix/Linux users, Emacs is more a way of life than an editor: It is possible to do almost everything from within Emacs, including, of course, programming, but also writing documents in mark-up languages such as HTML and LATEX; reading and writing email; interacting with the Unix shell; web browsing; and so on. I expect that this kind of generalized use of Emacs will not be attractive to most Windows users, who will prefer to use familiar, and specialized, tools for most of these tasks. There are several versions of the Emacs editor, the two most common of which are GNU Emacs, a product of the Free Software Foundation, and XEmacs, an oﬀshoot of GNU Emacs. Both of these implementations are free and are available for most computing platforms, including Windows. In my opinion, based only on limited experience, XEmacs oﬀers certain advantages to Windows users, such as easier installation, and so I will explain the use of ESS under this version of the Emacs editor.1 As I am writing this, there are several Windows programming editors that have been customized for use with R.

Using GNU Make to Manage the Workflow of Data Analysis Projects
JSS Journal of Statistical Software June 2020, Volume 94, Code Snippet 1. doi: 10.18637/jss.v094.c01 Using GNU Make to Manage the Workflow of Data Analysis Projects Peter Baker University of Queensland Abstract Data analysis projects invariably involve a series of steps such as reading, cleaning, summarizing and plotting data, statistical analysis and reporting. To facilitate repro- ducible research, rather than employing a relatively ad-hoc point-and-click cut-and-paste approach, we typically break down these tasks into manageable chunks by employing sep- arate files of statistical, programming or text processing syntax for each step including the final report. Real world data analysis often requires an iterative process because many of these steps may need to be repeated any number of times. Manually repeating these steps is problematic in that some necessary steps may be left out or some reported results may not be for the most recent data set or syntax. GNU Make may be used to automate the mundane task of regenerating output given dependencies between syntax and data files. In addition to facilitating the management of and documenting the workflow of a complex data analysis project, such automation can help minimize errors and make the project more reproducible. It is relatively simple to construct Makefiles for small data analysis projects. As projects increase in size, difficulties arise because GNU Make does not have inbuilt rules for statistical and related software. Without such rules, Makefiles can become unwieldy and error-prone. This article addresses these issues by providing GNU Make pattern rules for R, Sweave, rmarkdown, SAS, Stata, Perl and Python to streamline management of data analysis and reporting projects.

Emacs Speaks Statistics: One Interface — Many Programs
DSC 2001 Proceedings of the 2nd International Workshop on Distributed Statistical Computing March 15-17, Vienna, Austria http://www.ci.tuwien.ac.at/Conferences/DSC-2001 K. Hornik & F. Leisch (eds.) ISSN 1609-395X Emacs Speaks Statistics: One Interface | Many Programs Richard M. Heiberger∗ Abstract Emacs Speaks Statistics (ESS) is a user interface for developing statisti- cal applications and performing data analysis using any of several powerful statistical programming languages: currently, S, S-Plus, R, SAS, XLispStat, Stata. ESS provides a common editing environment, tailored to the grammar of each statistical language, and similar execution environments, in which the statistical program is run under the control of Emacs. The paper discusses the capabilities and advantages of using ESS as the primary interface for sta- tistical programming, and the design issues addressed in providing a common interface for differently structured languages on different computational plat- forms. 1 Introduction Complex statistical analyses require multiple computational tools, each targeted for a particular statistical analysis. The tools are usually designed with the assump- tion of a specific style of interaction with the software. When tools with conflicting styles are chosen, the interference can partially negate the efficiency gain of using appropriate tools. ESS (Emacs Speaks Statistics) [7] provides a single interface to most of the tools that a statistician is likely to use and therefore mitigates many of the incompatibility issues. ESS provides a

Embedding R in Windows Applications, and Executing R Remotely
Embedding R in Windows applications, and executing R remotely Thomas Baier and Erich Neuwirth February 15, 2004 R is object oriented, and objects are the standard way of packing analysis results in R. Many programming environments and applications programs in Windows can act as as (D)COM clients, which is the standard way of accessing objects exposed by (D)COM servers. Particularly, all Microsoft office programs are (D)COM clients and therefore can access any (D)COM server. Therefore, in encapsulating R as a (D)COM server is a natural choice to make R functionality accessible to other programs. To embed R in other programs, therefore, one of the key questions is what kind of objects are exposed to these applications hosting R, and how these objects are exposed. There are two different routes that can be taken here. We can either choose to expose R objects “as is”, with all their richness, or we can choose a min- imalist approach and only offer objects of types which can be handled easily by programs which normally do not employ rich object types for the data they usually handle. The difference can be very well illustrated when R is embedded in Excel. A spreadsheet essentially has 6 data types, scalars, vectors, and matrices of either numbers or strings. If we want to make R functionality a part of the spreadsheet functionality, it is sufficient that the R (D)COM server exposed this type od data objects. On the other hand, VBA (the programming language built into Excel) allows to work with any type of object.

Rstudio and .Rnw-Files
RStudio and .Rnw-files. The compilation of .Rnw-files requires that both LATEX and R are installed on the computer,1 and furthermore, the R-package knitr must be installed in order for the compilation to work. The example file Rnw_Example.Rnw (that you hopefully got a copy of together with this file), will in addition require that the R-package xtable is installed. There are several editors available for R and LATEX,2 but few of these can deal properly with .Rnw-files. Among editors that can deal with the .Rnw-files, the optimal editor is Emacs, http://www.gnu.org/software/emacs/ (with the packages Auctex, http://www.gnu.org/software/auctex/ and Emacs Speaks Statistics, http:// /ess.r-project.org), but this editor requires some time to get used to (the time invested in learning emacs will pay of quickly, so it’s worthwhile to learn how to use it). For newbies it might be easier to try RStudio, http://www.rstudio.com, which have a very simple solution for dealing with .Rnw-files, i.e. it’s “push a button”. But it’s important to be aware of some adjustments that must be made in the default settings before attempting to compile any .Rnw-file. Please consult the following support-page (and the links found there) https://support.rstudio.com/hc/ en-us/articles/200552056-Using-Sweave-and-knitr, in order to get up-to-date information about the present defaults in RStudio, since things might have changed after this document was written in January 2016.
