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:

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

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.

string size limits in RCurl
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

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

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>

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 - 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.

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:

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?

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

problem post request with RCurl
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

Doing seasonal adjustment from within R
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

Removing Embedded Null characters from text/html
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.
