similar to: loading R object files on an RWeb server

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

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 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

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

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, 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

Dear R-help, There seems to be a web page I am unable to download using RCurl. I don't understand why it won't download: > library(RCurl) > my.url <- "http://www.nytimes.com/2009/01/07/technology/business-computing/07program.html?_r=2" > getURL(my.url) [1] "" Other web pages are ok to download but this is the first time I have been unable to download a

Dear list, I'm trying to download a text file directly from the internet using the RCurl package and the command getURL. Duncan Lang graciously helped me solve the first step in this problem using the following command: ################# txtfile <- getURL('ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho/13e19.txt', ftp.use.epsv = FALSE) #################

Hello dear R-help mailing list. Looks like the same issue in Russian: library(RCurl) library(XML) u = " http://www.cian.ru/cat.php?deal_type=2&obl_id=1&room1=1" a = getURL(u) a # Here - the Russian is fine. a2 <- htmlParse(a) a2 # Here it is a mess... None of these seem to fix it: htmlParse(a, encoding = "windows-1251") htmlParse(a, encoding =

Dear list, I would like to call a Kerberos-authenticated web-service from within R. Curl can do it: $ curl --negotiate -u : "http://my.web.service/" so I would expect that RCurl also has the capability, but I have not been able to find the correct options to set. listCurlOptions() does not return anything with negotiate, and searching the source of RCurl, the only thing I found was

Hey fellas: I would like to integrate the following function: integrand <- function (x,t) { exp(-2*t)*(2*t)^x/(10*factorial(x)) } with respect to the t variable, from 0 to 10. The variable x here works as a parameter: I would like to integrate the said function for each value of x in 0,1,..,44. I have tried Vectorize to no avail. Thanks in advance, jose romero

Hi! I've performed a Google Scholar Search using a query, let's say "Frank Harrell", and parsed the links to the EndNote references from the resulting HTML code. Now I'd like to download all the references automatically. For this, I have tried to use RCurl, but I can't seem to get it working: I always get error code "403 Forbidden" from the web server.

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 environment, and a set of point

Hi all, I am using RCurl to try and download data from a website, but I'm having trouble finding out what URL to use. Here is the site: http://www.invescopowershares.com/products/holdings.aspx?ticker=PGX See how in the upper right, above the displayed sheet, there's a link to download the data as a .csv file? When I hit "copy url" and paste into getURL in R, it doesn't

Hello, I am having trouble getting the curlPerform function to authenticate using the .netrc file. From the documentation I've read it certainly seems as though this function should be able to authenticate via the .netrc file. The example I am using here comes from the "R as a Web Client- the RCurl package" paper and demonstrates using the .netrc file to access the

R-helpers, When I use cURL in the Terminal: curl --cookie-jar cookie.txt --url "http://corpusdelespanol.org/x.asp" --user-agent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:16.0) Gecko/20100101 Firefox/23.0" --location --include a cookie file "cookie.txt" is saved to my working directory. However, when I try what I think is the equivalent command R with RCurl:

Hi, I'm trying to download some data from the web and am running into problems with 'embedded null' characters. These seem to indicate to R that it should stop processing the page so I'd like to remove them. I've been looking around and can't seem to identify exactly what the character is and consequently how to remove it. # THE CODE WORKS ON THIS PAGE library(RCurl)

Hello list: Is there an easy way (preferably through one of the standard R packages) of obtaining summary statistics for grouped data? I could split the data into classes by hist, and then progressively calculate all the "columns" i need to obtain the mean and standard deviation, but i was looking for a single function that could do that with a data vector.
