similar to: No antialiasing with 2.7.0

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

I love the new tiff(), jpeg(), and png() in R 2.7.0 but found an issue that I didn't see reported. When specifying 'units = "in"' but forgetting to change the default height and width (so the figure is unintentionally going to be 480 inches by 480 inches) I run into problems. Here's the reproducible example: tiff("a.tiff", units = "in", res = 1200,

Hi all, I'm having trouble getting x11 to work with R. (This is on Debian testing.) I installed r-base and r-base-dev, and then r-cran-cairodevice. I also tried installing the Cairo package within R, which appears to work fine. This what I'm seeing: > capabilities() jpeg png tiff tcltk X11 aqua http/ftp sockets TRUE TRUE TRUE TRUE

Hello, I 've just re-installed R 2.9.0 on ubuntu 9.04. I do not understand why I am unable to use simple device function such as jpeg(), png()... > png() Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable to start device PNG In addition: Warning message: In png() : no png support in this version of R > capabilities() jpeg

I just installed R on Redhat Linux at work for the first time and have two questions. 1. I tried to install R to have png and cairo capabilities and was unsuccessful. Before running make, I ran ./configure --with-libpng=yes --with-x=no --with-cairo=yes --with-readline-yes . R installed fine, but when I run R and type capabilities() > capabilities() jpeg png tiff tcltk

Hi All, I have recently *re*-installed R-2.9.1 in my Linux machine. Since then, I am unable to plot using the usual interactive device. > plot(1:10) This plots in a pdf file "Rplots.pdf" in my working directory. > sessionInfo() R version 2.9.1 (2009-06-26) i686-pc-linux-gnu locale:

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),

Hello, I think there is a problem in recent devel builds of R on Windows with various devices from the grDevices package. For example: > capabilities() jpeg png tiff tcltk X11 aqua http/ftp sockets TRUE TRUE TRUE TRUE FALSE FALSE TRUE TRUE libxml fifo cledit iconv NLS profmem cairo TRUE FALSE TRUE TRUE

Dear all, I noticed that the r-base package for Ubuntu 8.04.1 do not have the tcltk support compiled in. Would it be possible to correct this? > echo "capabilities()" | R --no-save | tail -6 [Previously saved workspace restored] > capabilities() jpeg png tcltk X11 aqua http/ftp sockets libxml TRUE TRUE FALSE TRUE FALSE TRUE

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

Hi, I want to install the latest R in CentOS. Below is the command line: ./configure --prefix=/home/fino/R/3.2.5/ --with-tcl-config=/home/fino/software/tcl8.6.1/lib/tclConfig.sh --with-tk-config= /home/fino /software/tk8.6.1/lib/tkConfig.sh --with-readline=yes --with-cairo=yes --without-x Below is the output message when ran the above command: ... checking whether pkg-config knows about cairo

Hi, I'm installing R 2.10.1 under Linux but I don't know why my installation does not support png/cairo/jpeg: > capabilities() jpeg png tiff tcltk X11 aqua http/ftp sockets FALSE FALSE FALSE FALSE FALSE FALSE TRUE TRUE libxml fifo cledit iconv NLS profmem cairo TRUE TRUE TRUE TRUE TRUE FALSE

I am having trouble showing the Greek symbol "beta" correctly in the y-axis label of bitmap plots. Specifically, on my system the top of the "beta" symbol is cut off using the following example: file.jpg <- paste(tempfile(), ".jpg", sep = "") jpeg(file.jpg, h = 3, w = 3, units = "in", res = 300, type = "Xlib") boxplot(rnorm(10),

I'm running R 2.11 on Karmic. I'm having difficulty installing quite a few packages with the returned error message of "installation of package "[whatever the packages happens to be]" had non-zero exit status. I know this message sometimes is caused by incorrect or missing java packages and the like. I generally don't have issues with the installation of R or R packages

Good day, The code is : png("grainy.png", h = 600, w = 900) plot(1:10, main = "abcedfghijklmnopqrstuvwxyz", cex.main = 4, cex.lab = 4, cex.axis = 4) dev.off() and the server has the characteristics : > getOption("bitmapType") [1] "cairo" > sessionInfo() R version 3.2.3 (2015-12-10) Platform: x86_64-pc-linux-gnu (64-bit) Running under: Debian

Dear all, I am having problem on plots in R for some cases. For example: > plot( 1:10 ) > text( 1:10, letters[1:10], cex = 1) works well but : > plot(1:10) > text(1:10, letters[1:10], cex = 0.9) returns : Erreur dans text.default(1:10, letters[1:10], cex = 0.9) : impossible de charger la police X11 -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, de face 1 et de taille 11 (sorry

I apologize if this is too obscure to reproduce, or some idiosyncratic aspects of my system. If I create a plot, e.g., > plot(1:10) I get a graphics device as expected. I then click on the 'zoom' box on my X11 window, so the window expands to occupy the entire screen. The plot is redrawn at the scale of the large window, but is clipped to the 'unzoomed' size. I only

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 ...

What does capabilities() return? For example, I get > capabilities() jpeg png tiff tcltk X11 TRUE TRUE TRUE TRUE TRUE aqua http/ftp sockets libxml fifo TRUE TRUE TRUE TRUE TRUE cledit iconv NLS profmem cairo FALSE
