R {Rexpression;} > outfile

Image processing? Manipulating image data in R?
Hi!
I am looking for a R library by which i can load images (i found pixmap that
allows it to do).
But in addition i need methods to access the data, get them for example as an
array or matrix to do with this data some processing.
1. Is there a method in the pixmap library to access the matrix in which the
image data is stored.
2. Is there an alternative library running under MS Windows?
