Hi there,

  I have a binary image and I need to identify each clump of non-zero
values and attrib a diferent "patch" id-number.
  Is there a R package that do that? 
  By the way, what are the R packages for image manipulation?

Both rimage and EBImage (on Bioconductor) provide filtering and other 
tools. You may also find that you can use functions from the 
spatstat package such as solutionset() on your image, but it isn't 
obvious how to add the ID. A lot will depend on your specific application.
  Kind regards,

Have a look to adehabitat and the function labcon.
For image manipulation rimage may be useful.
