Dear list members I'm using CairoPDF to generate PDF (because of its font embedding and support for transparent colours). However, at least on my (Windows) system, the text it outputs seems to have completely wrong kerning. Here's an example: CairoPDF("test.pdf") plot(rnorm(100),xlab="Ovreset") dev.off()...

I have a small problem with R graphics output. When I use the lattice package and CairoPDF to generate publication quality graphs I often use the expression to create an axis title that has microlitres or micrometers as a unit. I use something like the following 'expression(paste("Length (", mu,"m )"))' as an argument to the xlabel function. The command works...

...basic questions about Cairo graphics engine. I'm trying to use the Cairo package to produce PDF output, mainly because I perceive it to be easy to use with a wide variety of fonts. But right now, I'm stuck trying to figure out what fonts are available to be used with Cairo, specifically the CairoPDF function. I've been able to successfully produce some test PDFs with grid graphics and CairoPDF (and the font "Georgia"), so my basic setup is working. I've tried to experiment with the CairoFonts() function but get the message: "the R Cairo package was not installed with f...

Dear R-Helpers, I have a problem with displaying the greek "beta" symbol in PDF files using Cairo library - it displays as an empty box. The same also happens for a dash symbol in subscript. Both symbols are displayed correctly if the plot is produced on screen (outside of CairoPDF). The syntax that I use for it in plot command is: 'xlab=expression(paste("A",beta,)[1-42])'. When I try to select a different font family using 'family' option in the CairoPDF command - it has no effect. I tried 'CairoFonts', but it displays an error: 'W...

Hello there, Straight to the point: it seems that CairoPDF from package "Cairo" cannot handle greek letters from expression(). For example, > eta = seq(from=-pi, to=pi, length=100) > f = sin(eta)^2 > pdf(file = "temp_pdf.pdf") > plot(eta, f, type="l", main=expression(f(eta)==sin(eta)^2), xlab=expression(eta), ylab...

...f() This figure should be a five by five block of grey squares. This is what I see in the R GUI device window, and when I open test.pdf in Abode Reader or SumatraPDF. However, when I open the file in Inkscape or Firefox, each of the squares is blurred. I tried swapping grDevices::pdf for Cairo::CairoPDF and got the same result. I also tried generating SVGs using both grDevices::svg and Cairo::CairoSVG, and also got the same result. I see the same thing using R-devel and R3.2.2 under Windows, and (with an older version of R) under Linux. I don't know whether the problem is with grid's ra...

...h multiple alpha values using Cairo to save them on a windows (32b XP) platform as it doesn't support more than 3 alpha values.

Hi, I have a vectors x and z, for example, x <- 0:20 z <- round(runif(20,1,7)) y <- 0.5 and I want to display z as an image. However if I then call image() with a vector image(x,y,t(z),zlim=c(1,7),col=heat.colors(7),xlab="Year",ylab="Action",yaxt="n",xaxs="r",yaxs="r") then I get the error Error in image.default(x, y, t(z), zlim =

dear R-experts---can someone please refer me to the latest installation instructions for graphics fonts in R (the pdf device)? (I would like to install the Charter font from the texlive 2011 distribution under OSX.) sincerely, /iaw ---- Ivo Welch (ivo.welch at gmail.com)

...d with this for a while, I decided to post it into r-help for the benefit of others, where google search will pick it up. thanks to everyone who made these facilities available.] The task is to use your own opentype otf fonts in an R-created pdf file using the pdf device (not with the [excellent] CairoPDF device, if only because it does not have colorspace [yet] and because it is not available elsewhere). ?Importantly, the fonts should be embedded. The example that follows embeds the bera fonts, which are freely available in the TeXLive 2011 distribution. ?It tries to check everything, so it should...

Hi, I'm using panel.polygon inside a custom panel function to generate filled polygons for an xyplot. Everything is as expected until I specify a value < 1 for alpha to fill with a semi-transparent color and output to pdf. The plot symbols appear malformed. Am I doing something wrong here? Thanks, Mark Here is an example (pdfs are attached): library(lattice) ## example data
