Please read the R FAQ which has an entire section devoted to this that I include below, copied and pasted from the txt version of the R FAQ. Personally, I'd go with Rpad. Dirk 4 R Web Interfaces ****************** *Rweb* is developed and maintained by Jeff Banfield <j...@math.montana.edu>. The Rweb Home Page (http://www.math.montana.edu/Rweb/) provides access to all three versions of Rweb--a simple text entry form that returns output and graphs, a more sophisticated Javascript version that provides a multiple window environment, and a set of point and click modules that are useful for introductory statistics courses and require no knowledge of the R language. All of the Rweb versions can analyze Web accessible datasets if a URL is provided. The paper "Rweb: Web-based Statistical Analysis", providing a detailed explanation of the different versions of Rweb and an overview of how Rweb works, was published in the Journal of Statistical Software (`http://www.jstatsoft.org/v04/i01/'). Ulf Bartel <u...@cs.tu-berlin.de> has developed *R-Online*, a simple on-line programming environment for R which intends to make the first steps in statistical programming with R (especially with time series) as easy as possible. There is no need for a local installation since the only requirement for the user is a JavaScript capable browser. See `http://osvisions.com/r-online/' for more information. *Rcgi* is a CGI WWW interface to R by MJ Ray <m...@dsl.pipex.com>. It had the ability to use "embedded code": you could mix user input and code, allowing the HTML author to do anything from load in data sets to enter most of the commands for users without writing CGI scripts. Graphical output was possible in PostScript or GIF formats and the executed code was presented to the user for revision. However, it is not clear if the project is still active. Currently, a modified version of *Rcgi* by Mai Zhou <m...@ms.uky.edu> (actually, two versions: one with (bitmap) graphics and one without) as well as the original code are available from `http://www.ms.uky.edu/~statweb/'. CGI-based web access to R is also provided at `http://hermes.sdu.dk/cgi-bin/go/'. There are many additional examples of web interfaces to R which basically allow to submit R code to a remote server, see for example the collection of links available from `http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/StatCompCourse'. David Firth (http://www.warwick.ac.uk/go/dfirth) has written *CGIwithR*, an R add-on package available from CRAN. It provides some simple extensions to R to facilitate running R scripts through the CGI interface to a web server, and allows submission of data using both GET and POST methods. It is easily installed using Apache under Linux and in principle should run on any platform that supports R and a web server provided that the installer has the necessary security permissions. David's paper "CGIwithR: Facilities for Processing Web Forms Using R" was published in the Journal of Statistical Software (`http://www.jstatsoft.org/v08/i10/'). The package is now maintained by Duncan Temple Lang <dun...@wald.ucdavis.edu> and has a web page at `http://www.omegahat.org/CGIwithR/'. Rpad (http://www.rpad.org/Rpad), developed and actively maintained by Tom Short, provides a sophisticated environment which combines some of the features of the previous approaches with quite a bit of Javascript, allowing for a GUI-like behavior (with sortable tables, clickable graphics, editable output), etc. Jeff Horner is working on the R/Apache Integration Project which embeds the R interpreter inside Apache 2 (and beyond). A tutorial and presentation are available from the project web page at `http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/RApacheProject'. Rserve (http://stats.math.uni-augsburg.de/Rserve/) is a project actively developed by Simon Urbanek. It implements a TCP/IP server which allows other programs to use facilities of R. Clients are available from the web site for Java and C++ (and could be written for other languages that support TCP/IP sockets). OpenStatServer (http://openstatserver.org/index.html) is being developed by a team lead by Greg Warnes; it aims "to provide clean access to computational modules defined in a variety of computational environments (R, SAS, Matlab, etc) via a single well-defined client interface" and to turn computational services into web services. Two projects use PHP to provide a web interface to R. R_PHP_Online (http://steve-chen.net/R_PHP/) by Steve Chen (though it is unclear if this project is still active) is somewhat similar to the above Rcgi and Rweb. R-php (http://dssm.unipa.it/R-php/?cmd=home) is actively developed by Alfredo Pontillo and Angelo Mineo and provides both a web interface to R and a set of pre-specified analyses that need no R code input. webbioc (http://www.bioconductor.org/) is "an integrated web interface for doing microarray analysis using several of the Bioconductor packages" and is designed to be installed at local sites as a shared computing resource. Finally, Rwui (http://rwui.cryst.bbk.ac.uk) is a web application to to create user-friendly web interfaces for R scripts. All code for the web interface is created automatically. There is no need for the user to do any extra scripting or learn any new scripting techniques. -- Three out of two people have difficulties with fractions. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
