Hi Paul,
Thanks for your info and script.
A year ago, I also felt that much of image processing is really missing in R.
At the moment, I am increasingly using now RSAGA, which is efficient, fast and
easy (+SAGA is still developing; +it works both on Linux and Windows OS). Here
are few example
Hi,
I'm currently trying to use save() on a density plot (i.e. an image) that takes
a long time to generate (using density(x)). I want to be able to use the saved
dataset as a covariate in ppm. However, once my image is saved and loaded back
in it is a character object instead of an image.
Thank you for all the incredibly valuable and helpful replies.
Summarizing the responses, it seems that kriging on river networks as well
as the group in Tokyo that is developing SANET are the closest exiting
projects on this topic.

Dear list,
I recently implemented a smoothing algorithm that could be interesting
for other people. It smooths a grid by calculating an average for a n x
n window. The input is a SpatialGrid/PixelsDataframe. For a 3x3 window
the algorithm creates 8 shifted matrices in addition to the original
