Hello, I am trying to access Microsoft Live Search Using SOAP through R. In R I am using the RCurl packages to make the calls. I have the following situation that looks crazy and cannot figure out how to solve it: #SOAP Request library(RCurl) h = basicTextGatherer() body='<?xml version="1.0" encoding="ISO-8859-15"?> <SOAP-ENV:Envelope

Hi, I am working with the RCurl package and I am using the curlPerform function for an soap-query. The problem is that the code is usually working well, but sometimes the connection gets lost. So I wrote a while-loop to repeat the query if anything might happened so that the same query runs again, but if the query-faults it takes a very long time for the repetition. My question is if there

Hi, Has anyone successfully used RCurl for posting data to a password-protected site? I have tired using option netrc=1 with both postForm and curlPerform (with postfields option) but can't authenticate. I would happily provide more details if some one has had some experience with this. Thanks very much. Valerie

Hi All, I am running into what appears to be character size limit in a JSON string when trying retrieve data from either `curlPerform()` or `getURL()`. Here is non-reproducible code [1], but it should shed some light on the problem. # Note that .base.url is the basic url for the API, q is a query, user # is specified, etc. session = getCurlHandle() curl.opts <- list(userpwd

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

Folks, I want to scrape a series of web-page sources for strings like the following: "/en/Ships/A-8605507.html" "/en/Ships/Aalborg-8122830.html" which appear in an href inside an <a> tag inside a <div> tag inside a table. In fact all I want is the (exactly) 7-digit number before ".html". The good news is that as far as I can tell the the <a>

Update taking into account the answer of Prof Ripley. ___________________________________________________ Below is a reproducing example that produces the crash. If I do exactly the same in R 3.1.2, it works perfectly. I have the lastest libcurl library (curl @7.40.0) installed So, perhaps indeed that the problem originates from RCurl, but the problem appears only in R 3.2. But before to

Dear all, I am having a problem downloading webpages through R when i run it in the DOS window under Windows Vista Basic. I have downloaded the batchfiles from http://code.google.com/p/batchfiles/ and have successfully set the PATH. I open up 'Command Prompt' in Vista and type (after the C:\...> stuff): ### START ### C:\Users\Karen>Rscript -e "library(RCurl);

Martin, Well, thanks for jumping in! We need all the help we can get ;) I changed the execute bit as you suggested and recompiled, no luck, still the same error message. Below is the output you wanted me to look at, its a bit beyond me so I include both a brief grep summary and then the whole enchilada. I do note that my output is different from yours, but I'm not sure how to interpret. I

Hi everyone, I'm trying to send an HTTP request using RCurl that only requests the response header, not the actual content. http://curl.haxx.se/docs/httpscripting.html says you can do this by using the following option: curl --head http://www.something.com/ However, I can't figure out how to do this when using 'getURL()', for example. Here's what I tried: FIRST TRY txt

     Hi everybody, I got a problem with the ftpUpload function from the RCurl package. My goal is to Upload a lot of files from a local directory to a web server. 1st try : for (i in 1:length(file)){       ftpUpload(what=files[i],to=files[i]) } At i=11 I get : (my server has only 10 available open connections available) : Erreur dans curlPerform(url = to, upload = TRUE, readfunction =

Hi everybody, I think that I am missing something fundamental in how strings are passed from a postForm() call in R to the curl or libcurl functions underneath. For example, I can do the following using curl from the command line: $ curl -d "Archbishop Huxley" "http://www.datasciencetoolkit.org/text2people"

Hello, I don't know if the problem originates from R-devel 3.2 or Rcurl itself.

Hi all, I'm running a complex script which accesses the internet, and sometimes it stops with the error: Error in curlPerform(url = url, headerfunction = header$update, curl = curl, > : Failure when receiving data from the peer Is there a way to make the script "wait" longer, or not crash when this error happens? (I'm wondering if this should be done in the level of

Dear R-Help, >From reading the help file, it is my understanding the the download.file() function does not support HTTPS connections. So therefore, understandably, the follow produces an error: ### R Code > url <- "https://stat.ethz.ch/pipermail/r-help/2008-October/thread.html" > destfile <- "//PFO-SBS001/Redirected/tonyb/Desktop/R_web_test/tmp.txt" >

Hi, I am trying to use a CGI service (Pubchem PUG) via RCurl and am running into a problem where the data must be supplied via POST - but I don't know the keyword for the argument. The data to be sent is an XML fragment. I can do this via the command line using curl: I save the XML string to a file called query.xml and then do curl -d @query.xml

Is anyone aware of a way to seasonally adjust time series data using X-12 ARIMA and TRAMO/SEATS from within R? I know that that one can seasonally adjust data with gretl, which I understand offers some level of R integration. However, all the examples I've seen of gretl/R integration involve working interactively with gretl, while here I want to work interactively with R and call gretl in the

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)
