[R] PNG-import into R

[Sydler, Dominik]

Hi there

I'm looking for a function to read PNG-bitmap-images from a file into R.
I only found:
 - the pixmap-package which cannot import png or similar formats
 - the rimage-package which can only import lossy jpeg-images (the
convertion from png to jpeg modifies the data!)

Is there any possibility to read PNG-files?

Thanks for any help
