[R] Add png image outside plot borders
I am trying to add a copyright disclaimer outside the plot borders of some images I have created. I can use mtext() to add the written portion, but I would like to have the Creative Commons license image (http://en.wikipedia.org/wiki/File:Cc.logo.circle.svg) before the text. I've found that I can plot a .png image inside the plot boundaries using rasterImage() but I can't figure out how to do it outside the boundaries. Any help would be great. If you know unicode or Adobe Symbol encoding for the CC logo, that might work too. ~Amelia McNamara Statistics PhD student, UCLA __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Add png image outside plot borders
If you run this, you'll see that I have some text at the bottom, but the logo is within the plot borders. plot(c(1.1, 2.3, 4.6), c(2.0, 1.6, 3.2), ylab=, xlab=) mtext(X axis label, side=1, line=3) mtext(Copyright statement, side=1, line=4, adj=0, cex=0.7) library(png) z - readPNG(Cc.logo.circle.png) rasterImage(z, 1, 1.6, 1.2, 1.7) I've tried doing things like rasterImage(z, 1, 0.5, 1.2, 1) but nothing shows up. The documentation for rasterImage() says that the corner values have to be within the plot region. As I said before, I want the logo to be down on the level of my copyright text, outside the plot region. Thanks!

Two angles I would try would be A) changing the regions or related but more flexible (and hence complex) B) use grid of course if you're making these with, say, ggplot2, you're already in grid (but then mtext probably would not work, though I have not tried it offhand). Anyway, an example (code please, not just the picture), will clear up all these questions and we can offer a solution tailored to what you are doing.

[R] Reduce the space under legend title
I would like to know if there is a way to reduce the space between the legend title and the first line of the legend, without reducing all the vertical space using y.intersp. Because of lack of space, I would like to differentiate my title by bolding it, and reduce the vertical space under the title to the space typically used between categories in a legend. plot(c(1.1, 2.3, 4.6), c(2.0, 1.6, 3.2), pch=c(1,2,3)) legend(x=bottomright, legend=c(Category 1, Category 2, Category 3), title=expression(bold(Fairly long title)), pch=c(1,2,3), bty=o) ~Amelia McNamara Statistics PhD student, UCLA __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Creating png of layered legend
Making the second layer of legend have full transparency seems to have fixed the issue. My first layer has to have a white background because I have a colored grid behind (sorry that didn't make it into my toy example). I did try to use type=Xlib, but I get the error libpng warning: Application built with libpng-1.2.26 but running with 1.5.2 My sessionInfo() is R version 2.13.1 RC (2011-07-04 r56273) Platform: i386-apple-darwin9.8.0/i386 (32-bit) locale: [1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base Thanks for your help, I never would have realized I needed to use a transparent background.

Have you tried specifying the background colour as a transparent colour? try bg=#FF00 - the first hex doublet is full transparency, the next three doublets can be anything - in both. Note that your example looks fine for me as you gave it - I suspect the MacOS quartz PNG driver is doing something different to the Xlib driver. Can you use type=Xlib on your png() function call? What's your R version? And sessionInfo() output?
