Re: [R] adding bmp/jpg/gif to an existing plot
Hi,
If you can first convert the image to ppm format, the pixmap package
has an addlogo function that can do just what you want,
x <- read.pnm(system.file("pictures/logo.ppm", package="pixmap")[1])
plot(1:10,1:10)
addlogo(x, px=c(2, 4), py=c(6, 8), asp=1)
One could probably get inspiration from the addlogo code to make a
similar function for EBImage.
Alternatively, you could use Grid graphics as shown in this page,
http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-grid:displaybitmap
I wrote a similar function for EBImage that you can use to annotate
ggplot2 graphics.
HTH,

Look at the subplot function in the TeachingDemos package.

Re: [R] adding bmp/jpg/gif to an existing plot
Look at the R-devel development version of R
o The graphics engine now supports rendering of raster (bitmap)
images, though not all graphics devices can provide (full)
support. Packages providing graphics devices (e.g., Cairo,
RSvgDevice, cairoDevice) will need to be reinstalled.
and
http://developer.r-project.org/Raster/raster-RFC.html
for more details (and older ways to do it less well).

How
to add a image file (jpg or bmp ou gif) to an existing plot window (not
plot over the image), like the code below (pseudo function add.image):
plot(1:10,1:10,main="test")
image = read.X("myimage.jpg")
add.image(image, x.left=2, y.bottom=4, size="40%") #points the left-bottom
corner and the reative size of image
abline(x=3, col=2, lwd=2) #continues editing the plot window.
text(2,3,labels="example of graphics and image")
Is it possible?
Thanks,
