RCurl slow when sending data over 1kb
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)),

Microsoft SOAP - Help!!
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:

h = basicTextGatherer()

RCurl - curlPerform - Time out?!?
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

Scraping a web page.
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>

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.

RCurl: using netrc with curlPerform
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

RCurl and postForm()
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:

Rcurl crash in R-devel
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.

[BioC] RCurl loading problem with 64 bit linux distribution
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.

RCurl: authentication when posting forms
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.

RCurl - HTTP request of header ONLY
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.

changing 'https' to 'http' when using download.file(), any side effects or just use RCurl?
Dear R-Help,

RCurl and cookies in POST requests
Hello.
I know that it's usually possible to write cookies to a cookie
file by removing the curl handle and doing a gc() call. I can do
this with getURL(), but I just can't obtain the same results with
postForm().
If I use:
curlHandle <- getCurlHandle(cookiefile=FILE, cookiejar=FILE)
and then do:
getURL(http://example.com/script.cgi, curl=curlHandle)
rm(curlHandle)
gc()
