point pattern interactions (Gcross and Kcross)
...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"...

Plot point patterns
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 coun...

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 funct...

mpl and ppp
...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

spatial simulation
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

Where can I find more documentation for speed up my server?
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
