similar to: [R] Catching a RCurl error?

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

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

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

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

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

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);

Hello, I don't know if the problem originates from R-devel 3.2 or Rcurl itself. I post this message to the R-devel list and to the author of RCurl (duncan at r-project.org). > library("RCurl") Le chargement a n?cessit? le package : bitops > print(sessionInfo()) R Under development (unstable) (2015-02-03 r67717) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under:

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

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 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 =

I am using RCurl's curlPerform command to send an XML string to an HTTP server running on the localhost. The command is something like this: reader <- basicTextGatherer() curlPerform(url="http://127.0.0.1/", httpheader=c('Content-Type' = "text/xml; charset=utf-8"), postfields=toString.XMLNode(xmlRoot(xdoc)), writefunction=reader$update,

Hi all, I was trying to run the latest version of RCurl on windows 7 with R 2.12 and got a "missing libeay32.dll" error. I now downloaded such a file from here: http://code.google.com/p/aion-inside/source/browse/trunk/out/libeay32.dll?spec=svn10&r=10 And placed it in the system32 folder. Now I get the following error: "The procedure entry point EVP_md2 could not be located in

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

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, 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)

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 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

I am having trouble with the postForm function in RCurl. I want to send a the command DELETE https://somewebsite.com.json but I can't seem to find it. I could try: postForm(url, _method="DELETE", .opts = list(username:password) ) but I get the error: Error: unexpected input in " postForm(url4, _" this error seems to be due to the underscore "_"

Dear list, I am trying to use RGoogleDocs, but I am connecting through a proxy server. I know RCurl is used for the connection, which should be able to deal with proxies and such. How do I set this up for RCurl? And can I use those settings with RGoogleDocs as well? I have the name of the proxy server and the port number. (Windows XP). thanks, Remko
