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...

Hi, I am working with the RCurl package and I am using the curlPerform function for an soap-query. The problem is that the code is usually working well, but sometimes the connection gets lost. So I wrote a while-loop to repeat the query if anything might happened so that the same query runs again, but if the query-faults it takes a very long time for the repetiti...

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

Hi all, I've just installed RGoogleTrends Version:0.2-1 (after compiling it for windows).

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. session = getCurlHandle() curl.opts <- list(userpwd = paste(user, ":", key,...

I am using RCurl's curlPerform command to send an XML string to an HTTP server running on the localhost. The command is something like this: reader <- basicTextGatherer() curlPerform(url="http://127.0.0.1/", httpheader=c('Content-Type' = "text/xml; charset=utf-8"), postfields=toString.XMLNode(...

...ames, destfile="") I don't know how to tell R to use the same names for the destfiles als the filenames. If i use: con = getCurlHandle( ftp.use.epsv = FALSE) contents = sapply(filenames[1:5], getURL, curl = con) names(contents) = filenames[1:length(contents)] I get an "error in curlPerform". I know, it's easy to download ftp folders with appropriate programs, but i want to manage to get it work in R.... greets Martin -- View this message in context: http://r.789695.n4.nabble.com/FTP-Download-tp2542359p2542359.html Sent from the R help mailing list archive at Nabble.com.

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: $ curl -d "Archbishop Huxley" "http://www.datasciencetoolkit.org/text2people"
