150+ R Abbreviations

Abbreviations exist in function names, argument names, and allowed values for arguments. This post expands on over 150 R abbreviations with the aim of making it easier for users new to R who are trying to memorise R commands. Context Abbreviations save time when typing and can make for less cumbersome code. However, abbreviations often make it more difficult to remember a command. Start [R-Node] Writing /var/www/r-node/data/cache/2/2d54f1d82cf67432cd4c82a000527112.i failed Unable to save cache file. Hint: disk full; file permissions; safe_mode setting. Writing /var/www/r-node/data/cache/2/2d54f1d82cf67432cd4c82a000527112.xhtml failed R-Node is a web front-end to the statistical analysis package R . Using this front-end, you can from any web browser connect to an R instance running on a remote (or local) server, and interact with it, similar to how you interact with R through the R console.

The R-Node server supports most standard commands, and should work with any package that provides textual output, or output via the standard graphing mechanisms. Graphs are created for the most part on the server, and are presented to the user over the network, where they can be saved by downloading. You can view the slides for a talk I did to the Palmerston North Linux Users Group if you are interested. R-Node. Introduction is a web interface for Hadley Wickham's R package ggplot2.

It is used as a tool for rapid prototyping, exploratory graphical analysis and education of statistics and R. The interface is written completely in javascript, therefore there is no need to install anything on the client side: a standard browser will do. A Practical Guide to Geostatistical Mapping.

Feb 02 2010 Information graphics, or infographics, are visual representations of information, data or knowledge.

Stunning Infographics and Data Visualization

The graphics are used where complex information needs to be explained quickly and clearly, such as on signs and maps and in journalism, technical writing and education. Today, infographics surround us in the media, in published works both mainstream and scientific and in road signs and manuals. They illustrate information that would be unwieldy in text form and act as a visual shorthand for everyday concepts, such as “Stop” and “Go.” Creating an effective infographic requires both artistic sense and a clear vision of what to tell the audience.

You can use it to determine how many people you need to interview in order to get results that reflect the target population as precisely as needed. You can also find the level of precision you have in an existing sample. Before using the sample size calculator, there are two terms that you need to know. These are: confidence interval and confidence level. If you are not familiar with these terms, click here. Enter your choices in a calculator below to find the sample size you need or the confidence interval you have. Interactive Statistical Calculation Pages.

It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package.

PSPP is a stable and reliable application. A brief list of some of the PSPP's features follows below. Support for over 1 billion cases. PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data. Downloading PSPP As with most GNU software, PSPP can be found on the main GNU ftp server: (via HTTP) and (via FTP). Documentation. Welcome. Homepage. Professor Rob J Hyndman. Dataplot.

R Commander

The R-Commander GUI consists of a window containing several menus, buttons, and information fields. (The menu tree, etc., are shown below.) The menus lead to simple dialog boxes, the general contents of which are more or less obvious from the names of the menu items. By default, commands generated via the dialogs are posted to the output window, along with printed output, and to the script window.

Introduction to Statistical Computing in R

Such packages make routine data analysis relatively easy, but they make it relatively difficult to do things that are innovative or non-standard, or to add to the built-in capabilities of the package. In contrast, a good statistical computing environment also makes routine data analysis easy, but it additionally supports convenient programming; this means that users can extend the already impressive facilities of R. Statisticians and others have taken advantage of the extensibility of R to contribute more than 2000 freely available “packages” of documented R programs and data to CRAN ( the Comprehensive R Archive Network) and many others to the Bioconductor package archive.

Precompiled binaries for popular Linux systems are available from CRAN, or users can compile R from source. See CRAN for details. Manuals. An Introduction to R. Table of Contents This is an introduction to R (“GNU S”), a language and environment for statistical computing and graphics.

An Introduction to R

R is similar to the award-winning1 S system, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, ...).
