similar to: R web interfaces for windows IIS

folks, I have been struggling with the "R" documentation for too long now and I need a simple answer on two questions. The documentation does not have adequate examples. Please help. given two equal vector lists: A <- c(0,1,2,3) B <- c(5,6,7,8) [Question #1] how do I dump them to a text file with the following format:

Hi, I have a (maybe stupid) question... Does CGIwithR package can be installed in R for Windows to work with a Microsoft IIS web-server? Or I need other libraries? Thank you, Gianluca.

Hello r-experts, I sure could us a little help. I have an ever updating text file with timestamped data in it. I can reformat in anyway I want if need be but currently I have chosen to make columns of date, time and measuresed value (comma delimeted and with the dates and times in quotes to interpret them as strings). Here is a small section of my text data file:

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

Dear R-Help, Does anyone know of a way to use CGIwithR in Windows? David Firth the author of CGIwithR states "It ought to be possible to adapt it for use also in conjunction with web servers running under Windows NT ... but the author has no plans for that." I have developed some applications in R that I would like to make available through a web interface using CGIwithR but at this

Dear alltogether, I want to use CGIwithR in conjunction with R2HTML. A small example called 'test.R': ##### #! /usr/bin/R invisible(capture.output(library(R2HTML))) HTML(summary(as.numeric(scanText(formData$numbers))), file=stdout()) ##### The script gets its input via 'CGIwithR.cgi' and contains the variable "numbers." The 'HTML' output (-> summary() in

<headline>Short question</headline>: Do people have advice on debugging R programs running after CGIwithR inputting of data from forms? Is there a way of setting up fast local versions if your local machine has to be a windoze (2k) machine (R 2.1.0) and your server is a Debian, ssh shell only set up running R 1.8.0? Are there simple guides to ways of not having to invoke R each

Hello I am able to construct a url that points to some data online in the JSON format. See an example at [0]. I would like to work with this data as a dataframe in R. I know that there is a package for handling json data [1] but it assumes the data is in a local file but It is not clear to me how to request the data from the web in an R script and get the json data converted into a data frame

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

Hi, I am having trouble to make the CGIwithR work in my server (Linux RedHat 7 - Apache), I installed the package, edited the R.cgi archive, but when I try to run any script from the browser I receive the following: Error message: Premature end of script headers: trivial.R Need I change some configuration of my system so that scripts work?

Hi, How can I install the server version of rpad on a website. I have read the instructions in http://www.rpad.org/Rpad/ServerNotes.html, but could not figure out how. Do I have to have something like Apache on the website? Is there any instructions in addition to those on http://www.rpad.org/Rpad/. Thanks, - Reza

I prefer to use R on a linux box and ultimately need things to end up there to serve things up using David Firth's excellent CGIwithR and apache, but one step at a time and I've installed 1.8.1 under win2k. Another question that I'm sure is simple: is there a simple way to find the list of installed libraries I had in my 1.7.1 installation and use that to drive install.packages?

Dear R users; I'm trying to use CGIwithR on a linux machine, I have followed the instructions on the package manual but still it does not run, the message that I get is as follows: The requested URL was not found on this server I used the example trivial, I put trivial.html under Web directory and trivial.R in cgi-bin directory, which itself is a subdirectory of Web directory, ( I have

Dear R users; I am using R for a project. I have some PHP forms that pass parameters to R for calculations, and publish the result in HTML format by CGIwithR. I'm using a Linux machine and every things work perfectly. However, it is too slow, it takes 5 to 10 seconds to run, and even if I start R from the Shell it takes the same amount of time, which is probably due to installing packages.

Dear R Users; Perl is the common language to write CGI scripts which handle Forms. My question is that can R be as fast as perl to do the same job(with using CGIwithR package). Is it an optimal solution to connect R directly to a commercial HTML webpages, Sincerely, Sean

Hi Rich, Take a look at the function fromJSON found in the rjson package. Note that the Usage in the help page: ?fromJSON names the second argument 'file' but if you look at the description the argument can be a URL.

I use CGIwithR to run a website that executes R scripts under cgi-bin. Are there any projects that implement a work frame using R similar to Java's servlet engine? Initialization times are hurting. Can initialize once process and treat all web requests as threads of this process? Any help with this subject is greatly appreciated.

I?ve been tinkering and discovered that the link I need to read json data from is ?https? and there is a certificate warning that I have to click through from a browser. That might be my issue. Is there any way in the json package to tell it to ignore self-signed cert errors in a url? -Rich From: Eric Berger [mailto:ericjberger at gmail.com] Sent: Tuesday, May 08, 2018 11:31 AM To: Evans,

Dear R-forum, I am looking for a good resource/help on working with POSIXct values and controlling the pretty x-axis labels and tick marks for a data VS time plots. Specifically, I wish to do programming logic which creates different vertical ablines calculations based on the range of times which i am working on. The default plot results are adequate, but I would love to make explicit calls on

Newbies (and others!) may find useful the R Reference Card made available by Tom Short and Rpad at http://www.rpad.org/Rpad/Rpad-refcard.pdf or through the "Contributed" link on CRAN (where some other reference cards are also linked). It categorizes and organizes a bunch of R's basic, most used functions so that they can be easily found. For example, paste() is under the
