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 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:
$ curl -d "Archbishop Huxley" "http://www.datasciencetoolkit.org/text2people"

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: 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.

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>

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
curl -d @query.xml

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:

httpheader=c('Content-Type' = "text/xml; charset=utf-8"),

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

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.

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.

I'm currently working on an R program where I have to access an FTP server

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,

RCurl format
I am having trouble with the postForm function in RCurl.
I want to send a the command DELETE https://somewebsite.com.json

but I get the error:
Error: unexpected input in " postForm(url4, _"
this error seems to be due to the underscore "_"
