...a non-directed graph] and I do not want to rediscover the wheel. I saw a large number of R packages dealing for instance with the k-means method or hierarchical clustering for spatially distributed data and I am basically facing a similar problem. I am given a set of data which are the positions of particles in 3 dimensions; I define two particles A and B to be directly connected if their Euclidean distance is below a certain threshold d. If A and B are directly connected and B and C are directly connected, then A,B and C are connected components (physically it means that they are members of the same...

Hello veryone, I am interested in the diffusion of particles inside a sphere, and its release through a small pore on the sphere surface. Unfortunately, I have not found the way to do this in R. Could you help me? Thank very much in advance for your help

...ors, one representing a single item and one representing a cluster centroid.) I may be misreading something fundamentally here, because aspects of the combined algorithm just don't make sense to me. It doesn't help my understanding that the paper seems to use overlapping references for the particle positions and clusters (eg in (3), (4) and I think (5)), and the cluster centres that are being used as particle data (at the bottom of p207). I think rewriting it with different variables might make this a lot clearer. (That may be the main source of my confusion, in fact!) As I understand it, t...

Hi all, Could anybody point me to some overview/survey papers about using particle filters and sequential monte carlo methods to estimate stochastic volatilities? I couldn't find any such articles giving a big-picture view of the literature. How do these estimation methods compare to EMM and other Bayesian methods for estimating stochastic volatilities? Also, I am looking...

Hi, Maybe this is more a programming questions than a specific R-project question, but maybe there is someone who can point me in the right direction. I have a picture of cirkels which I took with a digital camera. Now I want to use the diameter of the cirkels on the picture for analysis in R. I can use pixmap to import the picture, but how do I find the outside cirkels and calculate the

I am using the package Multicore/Parallel to do importance sampling. I have 5 cores on my computer. And I have let's say 10 000 particles to generate. What I did was to send 5 particles in each time, calling the package parallel. Which means in all I am calling the parallel command 2000 times. What happens is in the end somewhere along the way I end up with the error message error in fork unable to create a pipe. Would it be better...

Looks like people send many names in the contest, so shall I do too. I propose "Lepton", loosely meaning light (featherweight) in Greek. It is used in particle physics to refer to very light particles (electrons, muons). For me it also has the connotations of fastness and restlessness (in the LLVM sense of post-compile optimization). See more at: http://en.wikipedia.org/wiki/Lepton#Etymology Cheers, Gabor
