Hi, there, I am using PC window version R and dealing with big dataset usually. May anyone let me whether the maximal dataset size in R is limited by computer memory or hard drive capacity?

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

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

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 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 her data, and then her computer

Lately, I see a dependency problem with R-3.2 systems. install.packages allows dependencies, but they are not installed so the install fails. I see this a lot with students who are able to install packages like ggplot2 but then can't load it because a dependency "stringi" is missing. Those students are generally using Windows, but today I reproduced the same on RedHat Linux with

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, but I have not succeeded

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

Greetings, I am working on creating an interactive website that will generate R-code for users based in the information 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:

I set up a local repo for testing packages. My packages are not showing up from the repository when viewed by Linux clients. I suspect this is a web administrator/firewall issue, but it could be I created the repo wrongly. I am supposed to run write_PACKAGES separately in each R-version folder. Right? Maybe other novices can use these scripts, if they are not wrong :) Here's the file

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

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.liquidmarkets.com/m.php?m=News&file=article&sid=6 for up-to-date

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 kind of interaction with the underlying operating system (files,

Hello: What's the preferred way to link to package documentation from a vignette using markdown?

Hello list helpers, I'm working at a research institute and I've been asked to develop a way of using R as a scripting and analysis tool which takes information from users via web forms, perform a query to an Oracle Database running on a Linux server and finally return formatted reports to the user via web. I'm sort of a newbie in web forms and web services so i've been reading
