[R] Add png image outside plot borders

[baptiste auguie]

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
