search for: clumping

Sorry, I did not make my question clear. Since I have a point theme with many points, some of them may clump together. the problems here are: 1. how to find clumps in a point theme? 2. the convex-hull extension I found only deal with all the points in a theme at each time? how to make each convex hull around each point clump automatically? Thanks. Xiaohua On 5/12/06, Bob Booth <bbooth

I am trying to generate two dimensional random coordinates. For randomly distributed data I have simply used >xy<-cbind(runif(100),runif(100)) However I also want to generate coordinates that are more uniformly distributed, and coordinates that are more contagiously distributed than the above. Can anyone make any suggestions Thanks. Dr Terry Beutel Rangeland Scientist Animal

Dear all, I have a set od 30,000 binary landscapes, which represent habitat and non-habitat cover. I need to generate images that identify those neighbour (rule 8) pixels as one patch ID, and a different patch ID for each clump of pixels. I coded it using labcon(adehabitat), but as some of my landscapes have so many patches, labcon not finish and entry in a eternal looping. By other side, I coded

Dear all, How to generate one outline polygon for each point clump? Are there any present functions in ArcView, ArcGIS, R or some freewares? I just had a quick look at the package adehabitat and did not find the function. To my knowledge, I could do it as follows: 1) make a grid map of my study area with cell values = 0; 2) assign 1 to the cells containing at least one point; 3) convert the

...ed a bitmap because it tends not to clump? * is it due to the madvise on the host? If we were using the normal balloon messages, then we could, during migration, just route those to the migration code rather than bothering with the madvise. If they're clumping together we could just turn that into one big madvise; if they're not then would we benefit from a call that lets us madvise lots of areas? 4) Speeding up the migration of those free pages You're using the bitmap to avoid migrating those free pages; HPe's pa...

Dear R experts, I have been given data files in the following configuration and have been puzzling about how to read them in. First I will give a snippet of the beginning of file: Data File: W Para File: GABOR_0.gor v 10.6, Date : 29/10/2007 Time : 13:33 3.00 5.000 Noise SD (deg): 15.000 1 -5.321 -5.321 2 -5.321 -3.991 3 -5.321 -2.661 4 -5.321 -1.330 5 -5.321 0.000 6 -5.321 1.330 7

Right now in my view, I have a whole HUGE clump of <% if current_user %> and then <% if current_admin %> and then <% if current_teacher %> and then all that other stuff in my view. I have a ginourmous chunk of if and else statements in my views... is there a way to make it prettier? The if and else''s almost all have the same functions, expect for some minor changes.

A student is trying to cluster some data. Tree-building things seem to be pretty hopeless (we've tried most of the ones in R, I think). Multi-dimensional scaling produces somewhat tantalising results: things do clump together somewhat, but the clusters overlap a lot. I was wondering if these was an artefact of squeezing it down to 2D, and whether 3D might be better. So loc <-

I think I''ve found a mistake in the http://www.shorewall.net/ipp2p.html documentation. I''ve been trying to get traffic shaping working on the p2p traffic (Using ipp2p and wonder shaper) and lossing clumps of hair in the process. I followed the web page documentation but the "tcpost" rule that clasifies the packet and actually starts the "castration"
