...ns (in spatstat). I imported the data from two text files and created point objects using as.ppp. I then created a marked planar point pattern using ppp. I am fairly sure that everything worked, because when I ask for information about the data file, I get marked planar point pattern: 628 points multitype, with levels = w2004 w2005 window: rectangle = [ 607200 , 634800 ] x [ 3438400 , 3460400 ] (Note: the window values are so large because I am using UTM coordinates for my x and y locations) However, when I run gcross, I get the following error: code: g.0405<-Gcross(oakwilt, i="w2004"...

Hello! I want to plot a multitype point pattern called "new" in package spatstat. When I write plot(new) in the graphic window I can see a strech rectangle with a point inside, not the point pattern.If I write plot(new$x,new$y) the point pattern is plot ok.The problem is that I want do the density plots, quadrat count...

...tterns. What's in it: ------------ Functions for exploratory data analysis, model-fitting, simulation, spatial sampling, model diagnostics, and formal inference. Data types include point patterns, line segment patterns, spatial windows, and pixel images. Point patterns may include marks (e.g. multitype points). Spatial windows can have irregular shape (polygons with holes, binary images). Point process models can be fitted to point pattern data. Cluster models are fitted by the method of minimum contrast. Very general Gibbs point process models can be fitted to point pattern data using a functi...

...ppp' for my tree data, but when I try to put the 2 together in mpl, I get the following error message: "Error in as.ppp(X): Can't interpret X as a point pattern" which is odd because when I,in R, ask it to examine my object it reads: "marked planar point pattern: 55 points multitype, with levels = 1 2 3 4 5 6 window: polygonal boundary enclosing rectangle: [4943.5, 5023.4] x [4965.2, 5083.7]" which, as far as I can tell is a ppp. Can anybody shed some light as to why R would not like it? Is it the polygonal boundary? Thanks, Suzanne __________________________________...

Dear R-users, I'm trying to do some spatial simulation. I have two covariates, Z and C. I want to examine their relationship under different spatial distribution. I have no problem simulating completely spatial random process but I'm totally stuck on poisson (cluster) pattern. I already have a dataset with Z and C (obs=575) and I know the relationship between them. Using these 575

Hi every body from Samba Team, First thanks for this great software, that have add to us a more economical with great quality option than NT and Novell. I was working a lot on Samba for tuning it for the best performance for my network, but were I can find more documentation about performance for Samba on Linux Servers? Another quote, Samba runs on Silicons O2 Workstation? Thank's for any
