cairo

I am working with some R code that generates a number of images as png files; however, a Rplots.pdf file keeps on being generated in the working directory, is there a way to prevent this from happening? library(Cairo) CairoPNG(file = "graphs.png") nf <- layout(matrix(c(1:8), 2, 4, byrow=T), c(1, 1), c(1, 1, 1, 1), TRUE) for (k in 1:num.k) { plotMatrix(connect.matrix.ordered[k,,], log = F, main = paste("k=", k.vector[k]), sub = paste("Cophenetic coef.=", rho[k]), ylab = "samples", xlab ="samples") } y.range <- c(1 - 2*(1 - min(rho)), 1) plot(k.vector, rho, main ="Cophenetic Coefficient", xlim=c

I'm trying to use 'Cairo' package in Rstudio, using the command install.packages('Cairo') and it goes through with no problem. I get this message- The downloaded binary packages are in /var/folders/xn/c1nj85gx62b89876s15sbv9h0000gn/T//RtmpK9JM0l/downloaded_packages The package appears in the packages list, but when I try to include the package using library(Cairo) or library('Cairo') I get this error mesage- Error : .onLoad failed in loadNamespace() for 'Cairo', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3

I want to render parts of a svg file by name but for the life of me I cannot figure out how to do so (using python + gtk). Here's the svg file in question: http://david.bellot.free.fr/svg-cards/files/SVG-cards-2.0.1.tar.gz ( Update: this file no longer exists, but you can track it down at http://svg-cards.sourceforge.net/ ) On his site, David, says: You can draw a card either by rendering the file onto a pixmap and clipping each card manually or by using the card's name through a DOM interface. All cards are embedded into a SVG group. I don't know what he means by a DOM interface. I have done

I am using ggplot2 on ubuntu 12.04. By default my x11 type is set to Xlib. So when I use a smoother in qplot, I get an error like: "semi-transparency is not supported on this device: reported only once per page". However, if I call x11(type="cairo"), everything works fine. How do I get cairo as the default backend for x11? Define another function 'x11' which sets the proper type: x11 = function (...) grDevices::x11(...,type='cairo') To make this permanent, you could add the following lines to your ~/.Rprofile file: setHook(packageEvent("grDevices", "onLoad"), function(...) grDevices::X11

I need to take the output of a matplotlib plot and turn it into an SVG path that I can use on a laser cutter. import matplotlib.pyplot as plt import numpy as np x = np.arange(0,100,0.00001) y = x*np.sin(2*pi*x) plt.plot(y) plt.show() For example, below you see a waveform. I would like to be able to output or save this waveform as an SVG path that I can later work with in a program such as Adobe Illustrator. I am aware of an SVG library called "Cairo" that matplotlib can use ( matplotlib.use('Cairo') ), however it's not clear to me that this will give me access to the SVG path that I need, even
