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 Unfortunately the URL used in the example is no longer valid (i have emailed the maintainer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 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. But before to

[BioC] Rcurl 0.8-1 update for bioconductor 2.7
Hi Patrick, Greetings from !(sunny) Pittsburgh. What's the scoop on RCurl on windows (XP)? I've tried to install RCurl_0.92-0.zip and RCurl_0.9-3.zip, with both R 2.7.2 and R 2.8.0 from the RGUI (utils:::menuInstallLocal), and get the error "Windows binary packages in zipfiles are not supported". which (according to google's one and only hit) comes from a perl script.

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. Here's what I tried: FIRST TRY txt

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

Hi, for checking purposes, I setup a multiple sub-architecture R installation following this post from Simon Urbanek: https://stat.ethz.ch/pipermail/r-devel/2011-August/061755.html It all went fine.

How to set cookies in RCurl
Hi, I am trying to access a website and read its content. The website is a restricted access website that I access through a proxy server (which therefore requires me to enable cookies). I have problems in allowing Rcurl to receive and send cookies. The following lines give me: library(RCurl) library(XML) url <- "http://www.theurl.com" content <- readHTMLTable(url) content

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

ftp fetch using RCurl?
Hi everyone, I have to fetch about 300 to 500 zipped archives from a remote ftp server. Each of the archive is about 1Mb. I know I can get it done by using download.file() in R, but I am curious that is there a faster way to do this using RCurl. For example, are there some parameters that I can set so that the connection does not need to be rebuilt....etc. A even simpler question is, how can I
