[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
Hi Amelia, Can you give an example (using text where you want the CC is fine)? 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.

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!

Re: [R] Add png image outside plot borders
Amelia You can persuade rasterImage() (and other functions) to draw outside of the data region using xpd = NA or xpd = TRUE. See the help for the par function. D.

Re: [R] Add png image outside plot borders
Hi, if your logo is in vector format you should probably try the grImport package; see its vignette for examples, also below, library(grImport) ## http://creativecommons.org/about/downloads/ PostScriptTrace(cc.logo.eps) cc - readPicture(cc.logo.eps.xml) logo - pictureGrob(cc[16:18], x=unit(1, npc), y=unit(0, npc), width=unit(2,cm), height=unit(2,cm), just= c(right, bottom), use.gc = FALSE, gp = gpar(fill = grey40, col = grey50)) plot(1:10, rnorm(10), panel.first = grid.draw(logo)) HTH, baptiste On 19 September 2011 08:18, Amelia McNamara amelia.mcnam...@stat.ucla.edu wrote: I am trying to add a copyright disclaimer outside the plot borders of some images I have created.

Re: [R] Add png image outside plot borders
Great, thanks Amelia. Here is what I would do:
require(png)
require(grid)
## select the PNG file
z - readPNG(file.choose())
## Function to draw your statement
copyright.draw - function(label, image, x, y, size, ...) {
lab - textGrob(label = label,
x = unit(x, npc), y = unit(y, npc),
just = c(left, centre), gp = gpar(...))
logo - rasterGrob(image = image,
x = unit(x, npc) + unit(1, grobwidth, lab), y = unit(y, npc),
width = unit(size, cm), height = unit(size, cm),
just = c(left, centre), gp = gpar(...))
grid.draw(lab)
grid.draw(logo)
}
plot(1:10, 1:10)
copyright.draw(Copyright statement , z, .02, .04, .5, fontsize = 8)
Seems reasonably aesthetically pleasing to me (don't forget the space
after your copyright statement if you want there to be a space there
before the CC logo).
I kind like Baptiste's idea to use the SVG file directly, but you
asked for PNG. Also, the function is not strictly necessary, what is
nice about it is that it handles positioning the logo based on the
text. You don't want to be in a position where you are trying to
manually line the two up. You can pass additional arguments as you
like to gpar (though note it will affect botht he text and raster
grobs.
Cheers,
Josh
