similar to: kernel density estimation for univariate data using splancs

Dear forum, I would like to use the kernel2d or spkernel2d in the Splancs-package, but it does not recognize my polygon data. "Error in kernel2d(as.points(ptsbin), polygonprov, h0 = 2, nx = 100, : " is the error message. Invalid poly argument The data are defined as follows: polgonprov<-list(x=polyprov$X, y=polyprov$Y) with X and Y coordinates in the Lambert1972

Hi, I''m trying to build a (probably) secondary graphics passthrough install on an HP Z420. We don''t need earth-shattering performance. Unfortunately, the cards on the Xen tested list are going EOL and won''t be available from HP for the lifetime of the product we are building. HP have said that the approved graphics cards for the Z420 going forward are the nVidia

Hi Gordan, I wanted to let you know that today I decided to have a try for my GTX 680. Gigabite GTX 680 2048 MB GDDR5. I know that this particular card could be hard-moded to GRID K2 so VGA passthrough could work. Following instructions found on http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/420/ I just removed two resistors. Here is a screenshot

Hello, I''ve successfully passed a unmodified GTX 760 to Win7 x64. It involved some driver patching on the client side but I''m close to getting the required steps on the server side, too. Are there any legal issues that might arise from releasing a patch? Bob [image: Inline image 1] _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org

Hi Gordan, I received my Asus GTX 480 today (bought on ebay). Finally I succeeded in - quadrifying my GTX 480  into a Quadro 6000 ( softmod). - overpassing the 3-4GB of RAM on Windows XP 64 bits (domU) by applying a well known patch for Xen. - playing Crysis 2 and Darksiders II for a few minutes. http://img11.hostingpics.net/pics/953254ScreenshotXenSoftModedQuadro6000.png Using nvlfash I

Hello, I am trying to conduct a bi-variate ripley's k using the k12hat function in the splancs package (found here http://rss.acs.unt.edu/Rdoc/library/splancs/html/k12hat.html). Although, I receive an error when getting to the bboxx part of the code: poly <- list(x=c(fire4$X, nar4$X), y=c(fire4$Y, nar4$Y)) plot(seq(5,80,5), sqrt(k12hat(fire4), as.points(nar4),

Dear List, I'm trying to import a multiple polygon shapefile in splancs. I've found the following command but it seems to work only for single polygons: Name_of_splancs_polygon<-getPolygonCoordsSlot (getPolygonsPolygonsSlot(getSpPpolygonsSlot(name_of_sp_polygon) [[1]]) [[1]]) I've tried to change the numbers but it seams to choose polygons instead of importing them

Greetings: are there any simple ways to convert an sp class object to a splancs ppp class object, outside of reading the coordinates and computing a bounding box? cheers, -- Dylan Beaudette Soils and Biogeochemistry Graduate Group University of California at Davis 530.754.7341

Howdy Gurus I am try to compute envelope of Khat from simulations of complete spatial randomness using R package of "Splancs." I got the following error: > UL.khat <- Kenv.csr(length(X_coord), bnd, nsim=100, s) Doing simulation 1 Error in runif(n, min, max) : invalid arguments In addition: Warning message: NAs introduced by coercion I think that I have a problem with

>From version 2.01-17, splancs, a package for spatial point pattern analysis, depends on package sp. Because both packages have defined a bounding box function bbox(), the bbox() method in sp has been given priority, and the default object for dispatch is an array with two or more columns (as in splancs until now). However, the deprecated splancs function returned a non-closed rectangle of

Dear R Users; I have been using the space-time K-function analysis to detect the existence of clustering in both space and time. I wish to ask and know what the minimum number of cases should be for such analyses to be valid. I have data with 23 cases and don't know how careful i should be in the interpreting the results. Secondly, i wish to find out if there is any bond between the

Hi, I have a problem that concerns combination of the package Maptools and Splancs I have 2 shapefiles that i want to manipulate (one of type point and one polygon).I import them in R using Maptools but then i can't estimate a quartic Kernel using Splancs. The package doesn't recognize the shapes (invalid points and poly argument).I don't know if this is an easy task but i have

I''m using Xen 4.3, installed from source on Ubuntu 13.04. I''ve successfully installed a Windows 8 guest, and had Xen pass it an AMD FirePro W7000 GPU (technically 2 PCI devices - the second is for the sound), as well as the virtualised graphics adapter. Windows finds the card fine, and I''ve installed AMD''s drivers. Device Manager says that the card cannot

Dear all, I want my PhD thesis which I hand in tomorrow to look even nicer: Does polymap in the splancs library not allow horizontal plotting of y-labels? I have tried polymap(studyarea, xlab = "x (m)", ylab = "y (m)", las = 1) but it doesn't change the labels? Mayby some function in library(spatstat) support las? Thanks! Sincerely, Tord

Dear all, I had to place points at random, one in each of larger number of polygons (actually in objects of class 'SpatialPolygonsDataFrame' , see sp library), and tried first to do it using spsample (from sp). Surprisingly, every 5-15 trials, the output was a NULL value. The doc says that ' this may occur when trying to hit a small and awkwardly shaped polygon in a large

Hi, I would need some help with the splans package in R. I am using a Shapefile (downloadable at) http://rapidshare.com/files/215206891/Redlands_Crime.zip and the following execution code setwd("C:\\Documents and Settings\\Dejan\\Desktop\\GIS\\assignment6\\DataSet_Redlands_Crime\\Redlands_Crime") library(foreign) library(splancs) auto_xy<-read.dbf("Auto_theft_98.dbf")

I am trying to port the splancs library for S++ version 4.0 to R. I have modified the original FORTRAN to use dllwrap/dlltool (e.g. removed common blocks). I have been able to generate dll's (splancs.dll) using dllwrap/dlltool and Ming32 g77 with a -mdll switch. As of yet I have not been able to generate a dll that can be loaded by R. Does anyone out there have any suggestions. An example

I have a problem with function 'inout()' in package 'splancs' on CRAN-R Version 1.2.3 under FreeBSD4.3-STABLE. The following script produces and draws points and a polygon-surrounded area. Repeating the same script many times shows, that points on the polygon-line often, but not always, are outside of the polygon-area. library(splancs) # dataset with polygon (convex
