Hi, How are you? I have a quick question.... I have code that works perfectly with R desktop, but does not work with RWeb. Could you please tell me how to modify the code below so it will work with RWeb? #Read in txt file happyguys<-read.table("c:/test8.txt", header=TRUE, row.names=1) #Subset the txt file to only include certain values test<-subset(happyguys, GRADE == 7 & Y_Q10A < 9) #pr...

Hi, I got this working. i had to get rid of an underscore in one of my variable names to work on RWeb. Thanks for your help though!! Natalie __________________ I think you have to be either honest or careful, since the code you submitted to Rweb is different with your former code! Why the condition was changed from "test<-subset(X, GRADE == 7 & Y_Q10A < 9)" to "test&l...

Over the past year I have been working on a Web interface to R, Rweb. Anyone that is interested in trying it out can point their browser at: http://www.math.montana.edu/Rweb The main Rweb page provides access to three versions of Rweb. A simple text entry form that returns output and graphs, a more sophisticated Javascript version that provides a multiple window...

I cannot discover how to set or find the working directory in Rweb, so that I can source() a file from the server. The file I source() must refer to a data file in its directory. setwd() does not do anything, and getwd() says that the working directory is in /var/www/cgi-bin/ (on Linux). (I have a student who installed R on her own computer and analyzed half of...

...they input on the site. Currently, the R-code can be generated and downloaded to be run locally on a computer with R. However, I have noticed a number of applications out there that instead submit the code directly to an R-web server. Some examples seem to be: http://www.biostatisticien.eu/cgi-bin/Rweb/buildModules.cgi http://quantpsy.org/interact/mlr2.htm http://pbil.univ-lyon1.fr/Rweb/ I would like to do something similar and set up R-web on a university server to execute my code. My trouble comes in terms of finding out more information regarding how to do this. Most of my searches of Rweb...

Hi, RWeb web site is down past couple days, I am insterested in this project and want to try it for my projects. Deos anyone have this installation and user guide? Thanks! Best Regards, WeiQiang Li

I'm looking for an optimal approach to access Oracle databases via RWeb applications. I'm new to R but familiar with programming functions and web pages for the S+ Statserver. I'm now going through the motions of migrating S+/Statserver applications to R/RWeb as a feasability exercise. I can access databases using ODBC directly in R or S, and using Statserver,...

Hi, Sorry to bother all, but recently I found an interesting application of Rweb (although there are many other fancier web applications of R). We can submit some simple code to Rweb to create an HTML page containing animations. Most of Rweb servers I can find are still using very old versions of R, and the one at Tama University is an exception (it is using R 2.12.1): http://...

Hello list: I have some R code/data sets that i'd like to make available to others through RWeb server use.  The code/data were saved via "save.image" and should be made available by the following command sequence: con <- url("https:// ....") load(con) close(con) However, this is where the problem starts... For one thing, i am using google docs to host the R object f...

Hi, I'd like to execute simple commands and functions in R through a website, is there any service like this somewhere? I only found http://www.osvisions.com/r-online/ but it does not work (last update 2003) and the links to releated websites only give errors (if I calculate 7+3). Thanks for help & hints, Thomas

Hello; I'm thinking of setting up Rweb on an NT server and would like to know if any R users have done the same. I don't know much of Perl and cgi scripts so I'm wondering how much general debugging it wil take to build this interface. Any help would be appreciated. Thank you. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-....

I ported Jeff Banfield's Rweb (http://www.math.montana.edu/Rweb/) to Windows. In the process, I dropped some things (non-JavaScript version, Rweb modules and data sets), but also simplified the installation process by removing the dependency on NetPBM. A Ghostscript dependency remains, however. See http://www.liquidmarke...

We here at HGSI have a consultant doing some statistical work for us. HGSI bought and installed SAS, but our consultant insists that R and Rweb is a better solution. I do not know either package so I do not know, hence we are ditching SAS for R and Rweb. Any comments on this are welcom. Now for the real problem. Rweb is very expensive (time wise). The number of prereqs is way more than I thought when I agreed to this project. The compili...

Hello, I have a setup similar to Rweb ( http://www.math.montana.edu/Rweb/ ): I get R scripts from users and need to execute them in in a safe manner (they are executed automatically, without human inspection). I would like to limit the user's script to reading from STDIN and writing to STDOUT/ERR. Specifically, preventing any kin...

...: What's the preferred way to link to package documentation from a vignette using markdown? My current draft includes "[cumsum](https://stat.ethz.ch/R-manual/R-devel/library/base/html/cumsum.html)" to link to the help page for cusum{base} and "[KFAS](https://rweb.crmda.ku.edu/cran/web/packages/KFAS/KFAS.pdf)" to link to the pdf documentation for the KFAS package. This works, but it feels like an ugly hack, and I wonder if there might be some more elegant way of doing this (documented in a fine manual I have yet to find)? Thanks, Spe...
