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 e...

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...

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), bboxx(bbox(as.points(okpoly...

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 ta...

>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,...

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 coordin...

Hi! I want to use the package "SPLANCE" to do Ripley's K analysis I have a basic question about the package. I try to find how to do it, but I cannot. I hope you can help me.

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 ins...

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

...hit a small and awkwardly shaped polygon in a large bounding box with a small number of points', but in my case, the shapes were not really awkward, and the bounding box just the smallest rectangle including the shape, just the number of points was 1 in each polygon. Thus I tried csr (from splancs) after having extracted the polygon coordinates of each shape from the Spatial object, and everything went smoothly, with hit success every trial. Has anybody (anybody will probably be Edzer or/and Roger...) an idea why here splancs looks like outperforming spsample ? Patrick

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) # datas...

...h 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 results from the SatScan software and Splancs. In an exercise, SatScan suggested the presence of space-time clustering but Splancs did not present significant results. This might have been due to the small sample size or the way in which the spatial distances and times were specified for the analysis. Using the Burkitts data supplied with...

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!

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 i...
