similar to: Weighted LSCV 2d kernel smoothing

Thanks in advance. Nowadays I just calculate the bandwidth h of cross validation in kernel smoothing using R language. And I just looked up the usage of function, which is lscv(x,......, exact=FALSE) My question is what does "........" stand for and mean? do you mind specifically explaining it for me? Thanks Regards -- View this message in context:

Hi,  I am looking to perform a kernel density analysis in R, following the script that a friend of mine is using successfully. However, unlike for her, when I enter >kud<-kernelUD(data, h="LSCV"), R crashes and closes every time. This does not happen when I perform a different kernel analysis (>kud<-kernelUD(data)).. I have tried to un-install and re-install R, but it still

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 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

Hello, I'm new to R and am trying to use the adehabitat package for home range and habitat selection analysis for some animal radiotelemetry data sets I have, but I can't get the home range functions (mcp & kernelUD) to work with my data. I think that my problem is that I don't properly understand how the package uses data frames and factors, and I may not be defining the id

Hi List, I'm having problems installing certain packages. When I try to install fields, I get the output below. I have highlighted the what I perceive as the first error (spam seems to be a dependency of fields). Can I assume this is causing dependency problems for fields, which fails to install at the end, or is there a deeper problem? I run Ubuntu Karmic Koala on R 2.9.2. 2>

I am returning to using R after a little time away. Saw some great new functions in the fields package and decided to upgrade. Everything seems to go fine until I tried to actually load the package, when I get an error: >library(fields) Error in parse(file, n, text, prompt) : syntax error on line 227 And (of course) I am unable to access any of the functions in the fields package. Below is

Hello to everybody, I need to know the Smoothing Parameter to obtain Home Range of an animal through the Area Kernel. I have 200 locations with x and y. How can I obtain the Smoothing Parameter with R for LSCV, CV and Href method???

Hello, I was wondering if anyone has had success at running the LLVM within the windows xp kernel? The XP kernel really does not like C++ or exceptions and there is a project which attempts at getting C++ in there. In your humble opinion, do you think it can be done? My project is a reconfigurable device driver system which dynamically optimizes for the available hardware. two thirds is within

Hi, I had R working since version 1.4. Then I bought a new HD and installed a RH 7.3 on it and since then I can no longer install any R package. Here is the failure message I obtain: ... g77 -fPIC -O2 -m486 -fno-strength-reduce -g -c sortm.f -o sortm.o gcc -shared -o fields.so css.o csstr.o cvrcss.o cvrf.o dchold.o dcopy.o ddot.o dlv.o

Dear R-helpers, I'm having trouble compiling R packages from source on Win2K. I installed R 1.7.1beta [1] on my win2k machine [2], downloaded the fields package as source [3] and tried but failed to install the package [4]. I get the same problem with other packages, so it doesn't appear to be limited to fields. Installation of precompiled packages seems to work fine. I've been

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

We just upgraded our samba server from 3.0.14 to 3.0.21a and have discovered a subtle but very painful problem. Users of ESRI ArcMap (on fully patched Windows XP clients) are unable to read complex layered file data. Arcmap works fine with 3.0.14, it works fine with the data on a windows share, and it works fine when I set up a server to run the version of samba shipping with Solaris 9 (3.0.2! ).

Did not hear from anyone on this, so maybe we are the only ESRI users who got bit, but this turned out to be an issue with oplocks. Disabling oplocks on the server eliminated the problem.

Dear all, I've been using R on a Mac to process some data for export to ArcMap GIS (which only runs on Windows). ArcMap seems to require tab-delimited data (my data are in 3 columns), so I've been using the sep="\t" argument. However, this resulted in strange end-of-line characters when displayed on a PC. I looked in the write.table help file to find that eol="\r\n"

Hi all, I would like to 1. Read in an arcmap image into R (I can export pretty much any type of image jpeg, bitmap etc from arcmap) 2. Use R to create a nice colour legend in the plot First of all, Is this possible? So far I'm stuck on point 1. I have tried read.pnm() from pixmap and read.jpeg() from rgl. the pnm example provided works fine x <-

Dear users, I am trying to export polygons from Arcmap into Spatstat to run some simulations using functions available in Spatstat package. One particular area to be exported is formed by a number of polygons defining the external boundaries of the area (as a groups of islands) and a number of polygons inside the previous ones, as ?holes? not to be considered as part of the area. I have

Dear All, I am trying to visualize the surface of a bivariate kernel density estimate. I have a vector of bivariate observations(x,y), and a function which computes the kernel density estimate z corresponding to each observation. I cannot generate the (x,y) data in the ascending order needed by persp(x,y,z). I was wondering whether there is an R version of the S function interp. Would anybody
