XML htmlTreeParse fails with no obvious error
Hi all,
Sorry for the rather uninformative subject, but the error I get is not very informative either.
When using the XML and RCurl package to retrieve the content of an html page, htmlTreeParse fails, printing out the beginning of the HTML:
Error in htmlTreeParse(getURL(url)) :

Password protected R Repository
Hi,
I've set up a very simple R repository. Just a single source
library. Everything works fine. I can install the package on my client
using:
install.packages(repos='http://www.myServer.se/myRepo/',
pkgs='myLib', dep=TRUE)
However, I want to protect the repo, so I use a
.htaccess, placed directly under 'myRepo' on the server. I use

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.

Paste() - Get all possible combinations from multiple vectors
Hello fellow R-users,
Given are three vectors and the outcome would be all possible combinations in combination with the paste() function.
For example:
x <- c(1:3)
y <- letters[1:3]
z <- LETTERS[1:3]
My result would thus be 18 names based on all possible combinations between these vectors:
"1 a A" "1 a B", "1 a C", "1 b A", "1 b B",

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:

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: 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 Google Scholar's EndNote references
Hi!
I've performed a Google Scholar Search using a query, let's say "Frank
Harrell", and parsed the links to the EndNote references from the resulting
HTML code. Now I'd like to download all the references automatically. For
this, I have tried to use RCurl, but I can't seem to get it working: I
always get error code "403 Forbidden" from the web server.

Command that is conditional upon file retrieval: is it possible?
Hi all,
I'm currently working on an R program where I have to access an FTP server

files I access are at times inconsistent with regards to time posted, if
they post at all, etc.... Here's some of the code I use:

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

Hello,
I am trying to solve a problem but with no success for the past 4 days.
I use the RCurl package with R 2.8.1, and when I try to use the function

You don't check for malloc failure
Hi,
You don't check for malloc failure. I've made a patch that is possibly
wrong but it saves the program from SIGSEGV and replaces it with SIGABRT.
