similar to: Legend on plots when using Cairo

Hi All, I have been experiencing a strange issue ever since I upgraded my R and the packages. I cannot plot anything to the CairoPNG device.For an example:> Cairo(600, 600, file="plot.png", type="png", bg="white")> plot(1:10)> dev.off()will create an empty plot.png file. I am running R 2.12.1 (32bit) on Windows 7 (64bit). ----------------------------->

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),

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

Hello, I am generating .png images using the Cairo package in a for loop (looping on the number of zones, number of zones equals the number of plots to create based on different zone data). When I run the R script the .png files are created but they are all black? If I comment out the for loop and force my zones to equal one the png file is created correctly? Is there an issue with

Dear all, I am running something similar to this short example: library("lattice") library("geneplotter") X=matrix(cbind(1:100,100:1,c(1:50,50:1)),ncol=3) Y=matrix(cbind(1:100,1:100,1:100),ncol=3) names=1:3 dummy.df = data.frame(names = factor(names, levels = names), x = seq_along(names), y = seq_along(names)) xyplot(y ~ x | names, dummy.df, xlim = c(1,100),

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

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

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?

G'day all, I am working on a new FreeBSD 8.0 Server (remotely located), and have installed (now several times) R 2.11.0 but I cannot get any graphic outputs (everything else seems to be happening fine...) During install I have noticed and checked that png, jpeg, cairo etc libraries are available - here is the build output : R is now configured for amd64-portbld-freebsd8.0 Source

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

Hello all, I am using quartz (on OS X obviously) to produce PDFs and PNGs from my plots, for later inclusion in LaTeX. I am typically using something like: plot(0) dev.print(quartz, file="foo.pdf", width=5, height=3) dev.print(quartz, file="foo.png", width=5, height=3, dpi=72) I want the sizes of the PDF and PNG to be *equal* in *inches*, which works with dpi=72. However,

Hi, could it be that the text() fuction gives different output for normal png() and CarioPNG()? See the following example and the attached images: the font=2 and font=3 seem to be exchanged! Thanks for help, Thomas CairoPNG("Test-cairo.png",width=750,height=690) #png("Test-normal.png",width=750,height=690) plot(1,1,type="n",main="normal")

Dear list-member, I am currently developing a package with S4 classes. The NAMESPACE and DESCRIPTION is printed below. Within this package I have set a method "residuals" for two classes. In version 2.8.1 these two are reported whereas in R-Devel (2009-01-28 r47766). What have I missed? What has changed and how can I rectify the issue? Your help and pointers are welcome. For 2.8.1:

Dear R-users, though i have successfully installed Cairo_1.4-5 package on my Ubuntu machine, i become the following error message: Error in png(plot_name, width = 1600, height = 1200) : 'type = "cairo"' requires cairo >= 1.2 : try 'type = "cairo1"' By using png(plot_name, width = 1600, height = 1200,type = "cairo1") i become Warning message: In

Hello, I am creating plots of hourly precipitation and accumulated precipitation (on different axis, see attached image). I was wondering how can I have the plot frame (black border) start at zero, it looks like it is plotted less than zero? The code I use to create the png files is below: CairoPNG(PNG_file,width=1000, height=600, pointsize=14, bg="white") opar <-

Hi, when running the following on different instances of R (Linux and Windows), I get different results. The one for Linux seems to be the intended / documented one. When using numeric indices rather than characters, Windows seemed to behave as expected. -----------On Windows-------------- x = matrix(FALSE, nrow=3, ncol=3) colnames(x) = LETTERS[1:3] rownames(x) = letters[1:3] x # A
