[R] Loading an image/picture (png/jpeg/...) to screen...

[oliver]

Hello,


how can I load an external picture/image file to screen?

I want to use locator() then to get coordinates of that picture...
...in other words I want to use R to do some measurements on a picture.

Therefore I need to load the image into R display,
and that displaying needs to work together with locator().


How to do it best?

At the moment I need to be able to read in *.png files,
but if *.jpeg or other formats also will be supporttzed, this would be fine.
