similar to: Read from url requiring authentication?

I've added to R-devel the ability to use download.file() and url() to https: URLs, *only* if --internet2 is used on Windows. This uses the Internet Explorer internals, and only works if the certificate is accepted (so e.g. does not work for https://svn.r-project.org). Now I use IE (and Windows for that matter) only when really necessary, and Firefox has simple ways to permanently accept

Hi there I'm trying to configure R to get access to the internet. Using the Internet Explorer a proxy .pac script is used. Reading some older threads I found that I can use the --internet2 option. When choosing a mirror I get the error: "407 Proxy Authentication Required". This seems reasonable since I have to log in when using the IE as well. But where do I enter username and

Hi all, I am using RCurl to try and download data from a website, but I'm having trouble finding out what URL to use. Here is the site: http://www.invescopowershares.com/products/holdings.aspx?ticker=PGX See how in the upper right, above the displayed sheet, there's a link to download the data as a .csv file? When I hit "copy url" and paste into getURL in R, it doesn't

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

I am very new to R and have been struggling trying to read a basic ".csv" file from a password protected site with the following code: myURL ="http://www.frontierweather.com/degreedays/L15N15PowerRegionAverages_10weeks.txt" test2=read.table(url(myURL),header=TRUE,sep=",") A 'data.frame' is returned into the workspace, however it is not the data contained in

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]]

Dear List, Sharepoint sites are used more and more often by researchers as a platform to share all the information in a joint research project. Typically, they can be accessed only by a Hypertext Transfer Protocol Secure (HTTPS) URL. We are investigating whether it is possible to read and write data to Microsoft Sharepoint sites using R. We have managed to open a read-only connection to read

Hi, Does anyone know how I can go about securing web services created from ActionWebService?

I would like to know if there is a function that will run a linear regression and report the White (heteroscedasticity consistent) std. errors. I've found the hccm() function in the car library, but that just gives me the White covariance matrix. I'd like to be able to see the White std. errors without having to do much more work, if possible. Thanks, Brian

Are there packages that allow improved String and URL processing? E.g. extract parts of a URLs such as sub-domains, top-level domain, protocols (e.g. https, http, ftp), file type based on endings, check if a URL is valid or not, etc... I am currently only using split and paste. Are there better and more efficient ways to handle strings e.g. finding sub-strings or to do pattern matching? What

Hello R users, I am trying to read files from a website that requires authentication. I have been working with url() to to open a connection in Windows. For example: setInternet2(TRUE) con <- url(description="http://myusername:mypassword at www.somesite.com/myfile.txt", open="r") open(con) read.table(con, sep="\t") This works like a charm. My question is does

Hi I can't get R to connect to the internet. I am running R 1.7.1 on Windows XP and whenever I try to download packages etc from within R using the internet, it fails. OK so I am behind a firewall and use a proxy server.... SO, if I go to my MS-DOS prompt and type: RGui.exe --internet2 everything works....

I am trying to create a repository for my own packages as an easy way to auto install packages on a number of servers. Obviously, I am able to connect using install.packages() to CRAN without problems but when I specify my own repos I get an error: > install.packages(pkgs, repos="http://some.site.com") Warnings message: cannot open: HTTP status was '401 Authorisation

[Not sure if such wishlist item should go to R-help or R-devel...] It would be nice if an option can be added to the R for Windows installer that will add the --internet2 option to the command line in the shortcut that gets created. Also, is it possible to make that an option that can be set at the R prompt, or perhaps even better, as the default no matter how/where R is started? For those of
