Hola a tod@s! Estoy dando mis primeros pasos con R, y mi objetivo es conseguir descargar tweets de cuentas concretas de twitter. Encontre documentación sobre el package twitteR, y he intentado aplicarlo, pero siempre tengo problemas a la hora de conseguir la autentificación con OAuth. Este es el código que estoy utilizando: options( RCurlOptions = list(verbose = TRUE, proxy =

Dear all, I was intrigued by the ctree command and wanted to check it out. I first ran the demo with example(ctree) and did get the survival graphs in the end. Upon doing this with my own data and yielding a "Invalid operation on a survival time" I tried to rerun example(ctree) and now I also get "Invalid operation on a survival time" after the example runs plot(GBSG2ct)...

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 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.

Dear all, I am trying to install RCurl (because I want to install devtools) and to do so I've been informed that I must install one of the packages libcurl4-openssl-dev libcurl4-nss-dev No matter which one I install I get the following error from R: * installing *source* package ‘RCurl’ ... ** package ‘RCurl’ successfully unpacked and MD5 sums checked checking for curl-config...

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

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

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. Valerie

Dear list, I am trying to use RGoogleDocs, but I am connecting through a proxy server. I know RCurl is used for the connection, which should be able to deal with proxies and such. How do I set this up for RCurl? And can I use those settings with RGoogleDocs as well? I have the name of the proxy server and the port number. (Windows XP). thanks, Remko

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

Dear Rexperts, I am using R to query google. I am getting different results (in size) for manual queries and queries sent through "getForm" of RCurl. It seems that RCurl limits the size of the text retrieved (the maximum I could get is around 32 k bits). Any idea how to get around this ? Thanks in advance [[alternative HTML version deleted]]

Hi List, I am trying to leverage my knowledge of R in trying to use it for tasks that may not make R the best choice for these tasks. I wish to automate a web scraping task, which requires a multi-step procedure: 1) log in to a website 2) Go to a particular page 3) From the drop down menu, click on a particular link 4) From the tabulated data presented, choose relevant information based on a

Hello everybody, by the way, speaking about the r-cran-rcurl package in Ubuntu, the versions in trusty and vivid are linked by error to the "NSS" flavour of libcurl3 instead of the "OpenSSL flavour", which cause at least problems when using the CRAN devtools package. A bit more details are available in the Debian bug tracking system (https://bugs.debian.org/786473). I am not
