Hello: I'm running R 2.7.1 in Antix (Mepis kernel but heavily debian based). I have installed libcairo2 (1.6.4-6.1). I tried installing the Cairo package since I'm interested in generating some SVG graphs, and I got the following message: Only partial output (lines with no): .... checking if R was compiled with the RConn patch... no checking cairo.h usability... yes checking cairo.h

On Linux 2.13 by default links cairo, so png() uses it for rendering. One of my users has performance problem, so ask if it possible to temporary disable cairo during png() rendering so it reverts to grGraphics. My workaround for now is to configure R without cairo, but this affects all users that are forced to load and use CairoDevice if they wants better quality. I want to avoid this, is it

Hi all, I'm writing an interactive plotting function for viewing fMRI datasets. Currently, I get keypresses using grDevices::getGraphicsEvent(). Unfortunately getGraphicsEvent() only supports the X11(type="Xlib") graphics device on Unix systems. The Xlib device doesn't support buffering (i.e. dev.hold() and dev.flush()), so redrawing the plots causes lots of flickering. Is

Dear All, I am running Debian testing on my box and I have R 2.9.0 installed from the standard repositories. I downloaded the package source from http://cran.r-project.org/web/packages/Cairo/index.html but when I try to install it on my system, this is what I get $ sudo R CMD INSTALL Cairo_1.4-4.tar.gz * Installing to library ?/usr/local/lib/R/site-library? * Installing *source* package ?Cairo?

Hello, Sorry if it is not the right place.. I installed R-2.13.0 on a x86_64 linux server. All went fine, but the svg() function yells: > svg() Error in svg() : cairo-based devices are not supported on this build I have the Cairo, cairoDevice, RSvgDevice packages installed, and running. > Cairo.capabilities() png jpeg tiff pdf svg ps x11 win TRUE TRUE TRUE TRUE TRUE

Hi Taking a look at those patches is now on my todo list, so I may be in touch with both of you at some point to request some testing.

G'day all, I am trying to install the cairo package on FreeBSD and receiving an error to do with Makevars - (I'm not very good at this stuff) so here is my various bits of information. I guess this is a problem with a missing library, but I have just been through a lot of grief trying to get png and jpeg to work (they do now work!), so I'm not sure where to go for this. R

Hi The current status is that I am keen for people to contribute some testing code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951) There were also some getGraphicsEvent() changes/fixes suggested by Richard Bodewits (cc'ed), for which I am also seeking test code.

Excuse my asking here than on R-help, but it may be a Fedora question. On Fedora 7, I'm running a fresh R 2.7.1 built from source, usually in en_GB, but also tried in en_GB.UTF8. Running example(plotmath) generates lots of: Pango-WARNING **: shape engine failure, expect ugly output. the offending font is 'Symbol Not-Rotated ...' Setting: x11(type="Xlib") relieves the

Hello, So the Homebrew community dropped support for --with-cairo which is a shame because --without-x --with-cairo is an important combination for any environment that might need to generate graphics without X11 (or related) dependencies (macOS, headless linux servers). This rejected GitHub PR contains more detail: https://github.com/Homebrew/homebrew-core/pull/24094 (See also these comments:

Hi Just taking a bit more of a look at this today (currently fixated on making sure I can build some good regression tests). The best thing you can do is to keep reminding me like this :) Paul On 09/12/16 11:19, frederik at ofb.net wrote: > Hi Paul, > > Thanks for your efforts.

Thanks Frederick. Mark, if you have any examples to share, they would also be gratefully received.

Has anyone taken a shot at a Cairo graphics device yet? I half expected to see one on either Paul's pages or Omegahat. :-) --- Byron Ellis (ellis at stat.harvard.edu) "Oook" -- The Librarian

This question seemed to me to be more appropriate for r-devel than for r-help. My apologies if this is not the case. Recently I installed ``cairo'' on my lap-top so that I could make use of the (newish) polypath() function, with on-screen graphics. (The polypath() function does not work with X11(type="Xlib").) The installation went smoothly, X11(type="cairo") works

I have a question about antialiasing when R generates bitmaps. (This follows a thread on the ggplot2 mailing list.) I mostly use R on Linux, although I sometimes use it in Mac and Windows as well. On Linux, I've found that plotting shapes 15-18 via cairo results in bad-looking output. The points are not antialiased, and they are jagged and misshapen. Plots generated in Windows also aren't

Dear r-developers, I currently face an issue while compiling R from source on a debian wheezy. When running the configure script (particularly with --enable-R-shlib --prefix=/packages/R/3.1.0/) I get a Makefile and the output ... Interfaces supported: X11 External libraries: readline Additional capabilities: PNG, JPEG, NLS Options enabled: shared R library, shared

I posted previously about problems with X11() on my MAC using R 2.8.1 . After installing the securilty update for Tiger this morning, X11() now works from an xterm :-) However, I receive the following warnings with any plotting command using the default X11 settings. Fontconfig warning: no <cachedir> elements found. Check configuration. Fontconfig warning: adding
