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 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 "_"

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.

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 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)

RCurl::postForm() -- how does one determine what the names are of each form element in an online html form?
Dear R-Help,
I am looking into using the Open Calais web service (http://
sws.clearforest.com/calaisViewer/) for text mining purposes. I would
like to use R to post text into one of the forms on their website.
In package RCurl, there is a function called postForm(). This sounds
like it would do the job. Unfortunately the URL used in the example is
no longer valid (i have emailed the maintainer

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:

Could I get some assistance using postForm() to scrape the business names and addresses at this website:

RCurl : Problem with submitting using postForm()
Hi,
I am having trouble submitting a form using the RCurl package. My code runs
without errors but doesn't return the table I am after. I have a feeling it
is because there are 2 submit buttons on the page and I'm not hitting the
right one. I have tried everything I can think of to submit the form
correctly but with no luck.
My current code is as follows.

RCurl and kerberos
Dear list,
I would like to call a Kerberos-authenticated web-service from within R.
Curl can do it:
$ curl --negotiate -u : "http://my.web.service/"
so I would expect that RCurl also has the capability, but I have not been able to find the correct options to set.
listCurlOptions() does not return anything with negotiate, and searching the source of RCurl, the only thing I found was

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
