similar to: CairoPDF and greek letter spacing

Hi All: I have some 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

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=expression(f(eta))) > dev.off()

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() The v is (slightly) too far away from the O, it's much

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:

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, Please see the code snippet at the end of the email. I am using the color2D.matplot in Plotrix to plot a matrix. It works great, but there are a few things I cannot figure out (1) the value of cex.axis in the code snippet does not seem to affect the final pdf at all (at least on my system, Ubuntu 9.10, plotrix and Cairo installed from cran). How do I specify the size of the axis ticks

I've just been trying to post-process some R-created heatmaps using Inkscape, but I can't get them to display correctly in that software. To reproduce: library(grid) r <- as.raster(matrix(runif(25), 5, 5)) pdf("test.pdf") grid.newpage() grid.raster(r, interpolate = FALSE) dev.off() This figure should be a five by five block of grey squares. This is what I see in the R GUI

I sent this privately to ivo welch yesterday, and he thinks it might be useful to someone else as well. Since I'm on a Mac the screen device is quartz(): > quartz() > plot( c(0,1), c(0,1) ); > text( 0.5, 0.5, "\u2113" ) # and then File/Save As/ -- David.

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, We found a (to our eyes) strange behaviour that might be a bug. First a little bit of context. The 'units' package allows us to set the unit using both SE or NSE. E.g., these both work in the same way: units::set_units(1:10, "?m") #> Units: [?m] #> [1] 1 2 3 4 5 6 7 8 9 10 units::set_units(1:10, ?m) #> Units: [?m] #> [1] 1 2 3 4 5 6 7 8 9 10

I know that this has been asked before in other variations but I just can't seem to figure out my particular application from previous posts. My apologies if I have missed the answer to this question somewhere in the archives. I have indeed looked. I am running Ubuntu 11.04, with R 2.12.1 and ESS+Emacs. For journal formatting requirements, I need to italicize all the greek letters in any

Hi, Could someone please let me know how to plot greek letters in italic. text(0,14,expression(italic(rho)[italic(f)])) only plots the f in italic and text(37,40,expression(italic(rho))) doesn't plot rho in italic. I have checked demo(plotmath), ?plotmath, FAQ, and the archives 2004-2006 without finding the answer. I'm using R 2.1.1. and Windows XP. Thanks! Tord -- Tord Sn?ll

Hello, In the past I have used "expression" to include greek letters in axis labels, but this time I need to include the greek letter as part of a legend. Basically, I need to create the following vector to rename the levels of a factor: c("Interferon-gamma", "IL-10", "IL-5"), where "gamma" obviously needs to be printed as the greek letter

Hi, I would like to add a two-lines label consisting of: "Delta word1\n word2" (with Delta being the actual greek letter). However, when I try "expression(paste(Delta,"word1\nword2"))", I obtain the following display: "word1\n Delta word2". Do you have any idea on how to obtain the desired display? Thank you for your help! Sebastien [[alternative HTML

Hi everyone. I'm trying to use small letter phi in a graph produced in R. However, the small letter phi does not look as it should. In fact, it looks like this: http://r.789695.n4.nabble.com/file/n3963311/Untitled.png instead of what is here http://en.wikipedia.org/wiki/Phi Here's the code I use: expression(phi [1]) Anyone has an idea? With regards, Phil -- View this message

Hello. I am trying to get my axis label to read as follows (The symbol) Delta AUC blah blah... then below it...(some other text) The problem is the Delta symbol shows up beside the "(some other text)" rather than the "AUC". Does any one know how I can get the Delta to remain beside AUC? Here is the actual command should you care to look at it. par(mar=c(8,8,4,4))

Hi there, yet on the topic of greek letters and pdf plotting: when I run the following code pdf(file="temp.pdf") mu=seq(from=-pi, to=pi, length=100) plot(mu, sin(mu^2), type="l", xlab=expression(mu%in%(list(-pi,pi))), ylab=expression(sin(mu^2)), main=expression((list(mu,sin(mu^2))))) dev.off() I get a "proportional to" symbol in place of a

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 =

Hi This appears to be happening (at least) because cairo_pdf() delays initialising a Cairo surface until BM_NewPage(), rather than initiliasing a Cairo surface in BM_Open(), and replayPlot() triggers some activity (set clip region) on the device BEFORE a new page is started (so the pointer to the Cairo surface is null, so BOOM). Not sure yet whether to blame replayPlot() for not starting
