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),

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

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

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

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

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 installed R-1.4.0 and then updated all the packages I have, using update.packages(). I got an error for splancs and sgeostat. Trying to install them 'manually' with R CMD INSTALL, I got the following errors. 1) for splancs: Tue<15:26>library[82]#R CMD INSTALL splancs_2.01-5.tar.gz Installing *source* package `splancs' ... libs f95 -PIC -xO5 -dalign -xlic_lib=sunperf -c

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

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

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

Hi, I previously received help in extract data from a shapefile and now my question is about kernel density estimation. My objective is to have 3 kernel density plots; 2 for the each set of cases and the 3rd is the difference in kernel densities between the 2 sets of cases. Previously, I used the density function from the stats package, which worked but I wanted finer control of the bandwidth.

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")

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

In revising the splancs package, I use R CMD check. After a number of changes to various files in the directory tree, R CMD check fails at the * checking for undocumented objects ... ERROR stage as shown below. But running undoc() in R (pointed at the Rcheck directory, not on the older version) doesn't show the same error, and grep on the Rcheck R code finds the function. I ran undoc() under

Hi all, I'm trying to install the splancs contributed package on a Redhat 7.3 system with R 1.5.1 installed. I've installed the readline41-4.1-10 RPM which Redhat requires for R and it works great, thanks very much. However, when I attempt to R CMD INSTALL splancs_2.01-9.tar.gz as root, I get the following error message during the install: [snip] g77 -fPIC -O2 -m486

Dear R-Users, I wish to create a new family object based on the Binomial family. The only difference will be with the link function. Thus instead if using the 'logit(u)' link function, i plan to use '-log(i-u)'. So far, i have tried to write the function following that of the Binomial and Negative Binomial families. The major problem i have here is with the definition of the

Hi, I'm using latest Wine (20050310) with Debian sid (kernel 2.6.11). I own an USB 1.1 scanner : Agfa SnapScan 1212U. I successfully installed ScanWise software provided by the vendor (2.0.0.9 version) but when I launch it, it behaves as if the scanner's light wasn't on, or it was unplugged : it asks for me to connect the scanner. Below is the debugging info. I also tried to
