However, the spread of its use Prasenjit Kapat Meik Michalke thx among novice and occasional users of statistics have not progressed at the same pace, which The Ohio State University Heinrich Heine University Dusseldorf¨ can be atributed partially to the lack of a graphical user interface (GUI). Nevertheless, this situation has changed in the last years and there is currently several projects that have added GUIs to R. This article discusses briefly the history of GUIs for data analysis and then introduces the papers submitted to an special issue of the Journal of Statistical Abstract Software on GUIs for R. R is a free open-source implementation of the S statistical computing language and Keywords: GUI, statistical software, R. programming environment. The current status of R is a command line driven interface with no advanced cross-platform graphical user interface (GUI), but it includes tools for building such. Over the past years, proprietary and non-proprietary GUI solutions have emerged, based on internal or external tool kits, with different scopes and technological concepts. For example, Rgui.exe and Rgui.app have become the de facto GUI on the Microsoft Windows and Mac OS X platforms, respectively, for most users. In this paper 1. Introduction we discuss RKWard which aims to be both a comprehensive GUI and an integrated devel- opment environment for R. RKWard is based on the KDE software libraries. Statistical Nowadays, graphical user interfaces (GUIs) are the most common way of interacting with procedures and plots are implemented using an extendable plugin architecture based on a computer or other electronic devices. Whereas they are arguably not the best way of ECMAScript (JavaScript), R, and XML. RKWard provides an excellent tool to manage different types of data objects; even allowing for seamless editing of certain types. The performing every conceivable job, its dominance has reached the principal operative systems, objective of RKWard is to provide a portable and extensible R interface for both basic application domains, and tasks. Measured it in purely statistical terms, the triumph of this and advanced statistical and graphical analysis, while not compromising on flexibility and style of interaction is unquestionable and it seems clear that it will remain very popular in modularity of the R programming environment itself. the foreseeable future. However, regarding the discipline of statistics, this supremacy does not seem so dramatically Keywords: GUI, integrated development environment, plugin, R. clear, as many of the people working in this field seem to favor that using a typed language via a command line interface (CLI) is a much more productive, accurate and reproducible way of performing their tasks than a GUI. Actually, we are positive that they are right, because writing up commands can be undoubtedly much more productive than using a GUI, as far as 1. Background and motivation the learning cost is not included in the bill. Thus, although getting the knowledge to manage a command-based language is within reason if you are going to use it very often, the novice In mid 1993 Ihaka and Gentleman published initial efforts on the computing language and and occasional users of statistical software may not ever see sufficient returns to justify the programming environment R on the s-news mailing list.
