i am trying to install xml2 from CRAN, and it is throwing an error that it cannot find the libxml2 library configuration. The thing is that pkg-config seems to be set up correctly: $ echo $PKG_CONFIG_PATH :/usr/local/opt/libxml2/lib/pkgconfig:/usr/local/opt/libxml2/lib/pkgconfig $ pkg-config --cflags --libs libxml-2.0 -I/usr/local/Cellar/libxml2/2.9.7/include/libxml2

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

Full_Name: Craig Ruff Version: 2.7.1 OS: Irix 6.5.30 Submission from: (NULL) (128.117.8.145) Cairo based bitmap graphics output should work if cairo and R have been compiled without xlib support. 2.7.1 gives the "X11 is not available" message in this case when run interactively, and from my reading the png documentation, calling png(filename=..., type="cairo") should work.

Dear R users, I'm running R version 2.10.1. I tried installing the Cairo package and I got the following message: * installing *source* package ?Cairo? ... checking for gcc... gcc -std=gnu99 checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for

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

Hi, on Windows XP Pro with R version 2.7.1 Patched (2008-06-27 r46012) the 'Cairo' and the 'EBImage' packages does not play well together. Loading EBImage before Cairo cause the following to happen: # Rterm --vanilla > library(EBImage); > library(Cairo) Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library

I am trying to install the Cairo package on a linux machine, the Cairo package did not install correctly (could not find cairo.h), I am new to R and linux any help on the installation would be great. Below are output from trying to install the Cairo package, thought this might help. > install.packages("Cairo") Warning in install.packages("Cairo") : argument

Hi, I have installed the latest version of libglib-2.0 (2.28.0) and cairo 1.10.2 Then I have compiled R 2.12.1 But when i I try to install Cairo (1.4-6) I get the following unreferenced Symbol error: *** installing help indices ** building package indices ... ** testing if installed package can be loaded Error : .onLoad failed in loadNamespace() for 'Cairo', details: call:

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

Hi All, I just installed Cairo on R 2.5.1 on windows XP. My hope was to get to see the transparency output e.g. http://had.co.nz/ggplot2/stat_smooth.html ggplot2 - stat_smooth , which I finally managed to do. However, I find the Cairo device, which I access either through CairoWin() or Cairo(type="win"), is pretty shaky in a number of respects : - whatever portion of the Cairo

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

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

I think I found a bug in the Cairo library, plus weird behavior in both the Cairo and the normal pdf device. The baseline of the spades symbol seems to be off. This is easier to show than it is to explain. The problem does not appear in the normal pdf device, which is why I am guessing this is a Cairo bug. moreover, I cannot figure out why three of the card symbols seem to be transparent, but

Hi R friends, I've been attempting to create plots with multiple alpha values using Cairo to save them on a windows (32b XP) platform as it doesn't support more than 3 alpha values. This worked well until I wanted a postscript file (unsupported) and as a attempted work around I installed RGtk2. So far so good, however now when I try to use a >CairoPDF("alpha.pdf", 6, 6,

Dear all, I am trying to use the Cairo package to avoid some X11 issues and it works very well. However, when I want to add a legend to my plots, I receive an error message from Cairo: > library(Cairo) > CairoPNG(file="test.png") > plot(1:100) > dev.off() null device 1 This works fine. But: > CairoPNG(file="test.png") > plot(1:100) >

Hi, Has anyone else run into this weird behaviour where the text in the plots created using Cairo are always italicized. For example, library(Cairo) Cairo(file='cairo_created', type='pdf', dpi=100) plot(1:10) dev.off() This produces the following attached 'cairo_created.pdf' graph. Notice how the text is italicized. The same code but using pdf() as the graphics

Hi, It seems that anti-aliasing in png(type = 'cairo') is not well supported for the point symbols without boarders, e.g. pch = 16. The Cairo package works well, though. You can compare png() with CairoPNG(): png(): http://i.imgur.com/8niB3jX.png CairoPNG(): http://i.imgur.com/FZBJOxm.png f = function(dev, ..., main = '') { dev(...) plot(c(1, 2, 1, 2), c(1, 1, 2, 2),

All- I have been hacking on an R 2.15 build on an Ubuntu 10.4 box, and I do not know how to debug R's error message regarding cairo "working". Configuration completes without the expected additional capability (cairo) R is now configured for x86_64-unknown-linux-gnu > Source directory: . > Installation directory: /app/vendor/R > C compiler:

In several tries, I am finding the locator and identify functions on the cairo device on Windows, with R-2.13.0, do not seem to work correctly. Here is my experience with locator where I click the four corners of the device window. First, with the windows() device, the results are consistent with what I see on screen > windows() > plot(1,1) > locator() $x [1] 0.6075000 1.3981252
