similar to: Finding the right url for RCurl

Hi all, I'm currently working on an R program where I have to access an FTP server to download some of the data I need. However, the people who post up the 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: library(RCurl) url1 = paste("ftp://user:password at a.great.website.com/",

Hi all, I'm looking at a large data set, and I'm interested in removing rows where only one variable is duplicated. Here's an example: > presidents Qtr1 Qtr2 Qtr3 Qtr4 1945 NA 87 82 75 1946 63 50 43 32 1947 35 60 54 55 1948 36 39 NA NA 1949 69 57 57 51 1950 45 37 46 39 1951 36 24 32 23 1952 25 32 NA 32 1953 59

Hi all, I'm trying to write a function that will search and extract from a long character string, but with a twist: I want to use the characters before and the characters after what I want to extract as reference points. For example, say I'm working with data entries that looks like this: Drink=Coffee:Location=Office:Time=Morning:Market=Flat

I have some problem in running R-cran's Demography package. The hmd.mx function need Rcurl. I tried to install RCurl, but meet the following error: ********************************************************************* ... * installing *source* package ?RCurl? ... checking for curl-config... no Cannot find curl-config ERROR: configuration failed for package ?RCurl? * removing

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, 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

According to [1] and [2], using RCurl to post a form with basic authentication is done using the postForm method. I'm trying to post generated interpolation data from R onto an HTTP form. The call I'm using is page <- postForm('http://our.server.com/dbInt/new', opts = curlOptions=(userpwd="test:test", verbose=T), profileid = "-1", value="1.801",

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 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]]

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

Dear R-Users, I am having some trouble getting an installation of RCurl 0.8-1 to work properly on a Debian (Etch) machine.

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

There are some CSV file from the link below. I'm having trouble installing the package. Is this the package I have to use or is there another one I need to use?

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 "_"

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

I have 64-bit R 2 12 0 installed on Solaris 10 of Sun Sparc. When I tried to install RCurl, it failed with the following lines, ...............

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, 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. The only change I made to Simon's procedure was to install with: make prefix=~/bin/R/2.15 install instead of sudo make install rhome=/usr/local/R/2.15. I am now trying to install RCurl in

Hi all, I was trying to run the latest version of RCurl on windows 7 with R 2.12 and got a "missing libeay32.dll" error.

Now I get the following error: "The procedure entry point EVP_md2 could not be located in
