similar to: ReadLines does not give results with urls

Dear all, as the bug # 7991 is flagged not-reproducible, let me give you some pieces of code, as I have the same or similar problem. The problem always shows up with the first example (a small text file) and only sometimes (but without obvious pattern) with the second example, which is a binary file. > download.file("ftp://ftp.nhc.noaa.gov/pub/atcf/btk/bal012006.dat",

Hello everyone, I get (reproducible) segfaults when I try to update my packages, and was wondering whether anyone knows why this might be happening. I am trying to update my packages: 1. I start R via sudo in a terminal 2. I type update.packages() - a Tcl/Tk list pops up, I select a mirror 3. R segfaults. Maybe I need to update to a newer version of R or something? Slightly OT, but does anyone

Dear List, I have problems with the function source() using a url of the kind: http://localhost:5984/path/fn.R I receive Fehler in file(file, "r", encoding = encoding) : kann Verbindung nicht ?ffnen Zus?tzlich: Warnmeldung: In file(file, "r", encoding = encoding) : ?ffnen fehlgeschlagen: HTTP Status war '502 cannotconnect' The url itself is ok since I can: -

Hi there, I have had a problem with loading the package XLConnectJars_0.2-0.zip from the CRAN mirrors. The problem occurs when executing utils:::menuInstallPkgs() I have traced the problem down to the "download" internal command. It appears that files over approx 15 MB are being truncated. The exact point of truncation varies slightly but the truncation is on a 4096-byte boundary. I

Hi, I am trying to use R at work and at home on the same computer. At work, I have a proxy, and at home, I do not. I have, for work, a User environment variable "http_proxy" which I set in the OS (Windows XP Pro). When I am at work, and I try to retrieve data from the web with 'read.csv', things work just fine. I assume it knows how to use the proxy. The trouble is when I

Hello, I have been trying to download a pdf file but I only receive a blank sheets. I used the option internet2 in windows: Rgui.exe --internet2 but I recieved the same result. I use the next command: ulr2 <- "http://cran.r-project.org/doc/manuals/R-intro.pdf" download.file(url = ulr2, destfile = "D:\\users2\\r-intro.pdf",cacheOK = FALSE) Any ideas how I can resolve

I am new to R and have been spinning my wheels on the following. *Issue:* I have a membership to a website, and I want to grab data from the website using download.file(). download.file(url, destfile, method, quiet = T, mode = "w", cacheOK = TRUE) The R Documentation is helpful. However, I have been unsuccessful in figuring out how to access the website using my username and

The patch below adds support for custom HTTP headers in download.file() and url(). My main motivation for this is performing basic http authentication. Some web sites do not support embedding the credentials into the URI itself, they only work if the username and password are sent in the HTTP headers. In fact specifying the username and password in the URI has been

Hi I want to start the buil-in iexplore.exe. I created a new .wine directory and typed #wine iexplore.exe Then it tries to download the Mozilla ActiveX PlugIn and this is where the problem starts: The download window shows, but it doesn't start the download. I am sitting behind a proxy server (no authorisation needed), and the proxy is setup correctly: ftp_proxy=ftp://proxy.sun.ac.za:3128

Wrap the command around an heredoc only if setarch needs to be used; otherwise the heredoc will not be run at all.

When running (eg) dnf on a 32 bit i686 guest when the host is 64 bit x86_64, dnf believes it is running on a 64 bit machine and so tries to install x86_64 packages. We can 'trick' dnf into believing it's a 32 bit machine using the setarch program. $ virt-builder fedora-22 --arch i686 --install 'gperf' ... [ 27.4] Installing packages: gperf ...

There have been quite a few questions recently about this, so I have tried to gather experience. I set up a proxy using Apache2 (a very common server) behind our firewall and tried various authentication approaches. One comment: all the methods return error messages when they fail. Please don't report `it doesn't work' without the full details. 1) For a proxy that authenticates

Dear R-Users, I think I have encountered a potential bug (or at least unwanted behavior), but I'm not sure so I wanted to post here first. Lately I've been encountering an error when running a package I put together. I have my package set up to check for updates when it loads but this error occurs and stops the package from loading: Error : .onLoad failed in loadNamespace() for

These are now passed using a curl configuration file, which is a little bit safer than using command lines. virt-builder doesn't need to pass usernames and passwords to curl, but if it ever does in future this will be a lot safer. --- builder/Makefile.am | 1 + builder/builder.ml | 6 +-- builder/downloader.ml | 94

Add an helper function to run a command in the guest, checking for the host/guest compatibility. This is mostly extracted from the internal do_run helper currently in the Customize_run module of virt-customize. --- mltools/tools_utils.ml | 50 +++++++++++++++++++++++++++++++++++++++++ mltools/tools_utils.mli | 10 +++++++++ 2 files changed, 60 insertions(+) diff --git a/mltools/tools_utils.ml

First of all, I apologize for the triple post, but I did not see that the word wrap on the r-help list site would render my code unusable. So here it is again. Hoping that this time it will work if you cut and paste it in your Rgui. I have a program that works well in Rgui but that does not work in a batch file (Execution halted). Here's the code (it will work on your R, but you need

I have been trying to get the R and package update functions in the GUI version of R to work on my Mac. Initially I got error messages that suggested I needed to set up the http_proxy for GUI R to use, but how can this be done? I eventually got to the point of writing a .bash_profile file in the Bash terminal and setting the proxy addresses there. I can now use my Bash terminal, invoke R,

Move the Curl wrapper module from virt-v2v to mllib. Use the module when virt-builder issues curl calls. Rich.
