similar to: R crashes with >kud<-kernelUD(data, h="LSCV") script

Hello, I am working through examples of generating Home Range using the adehabitatHR package. Everything is going fine until I load the code for the kernelUD function, it looks like this; > data(puechabonsp) > kud <- kernelUD(puechabonsp$relocs[,1], h="href") > kud I then get an error of; Error: could not find function "kernelUD" Any thoughts on what I am

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:

Dear R experts, I'm using the adehabitatHR package in order to perform a kernel analysis and estimate the home range of my input data (GPS relocations of 42 individuals). I've done the analysis for one of the individuals and it worked perfectly (see code below). But now I'm trying to use a list and call the function lapply to do the same thing through all the 42 individuals (also see

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

Thank you for providing the example code... for the request of running it multiple times it would have helped if you could have confirmed that the example ran through without errors... there were a lot of mistakes in it. Look into using the reprex package to check your example next time. I don't do this kind of analysis... I really don't know what to expect from the functions. The

Dear all, I have a data similar to this: myframe<- data.frame (ID=c("Ernie", "Ernie","Ernie","Ernie"), Timestamp=c("24.09.2012 08:00", "24.09.2012 09:00", "24.09.2012 10:00", "25.09.2012 10:00"), Longitude=c("8.481","8.482","8.483","8.481"),

R List, I am seeking help in the area of kernel smoothing. I am attempting to use LSCV values to conduct 2d and weighted 2d kernel smoothing (imported from an ArcMap shapefile), and have been unable to find tools to conduct such analysis in R. My biggest problem is determining the LSCV value and finding a tool that does weighted smoothing, as there are obviously many different packages that will

Dear all, I have just uploaded 4 new packages on CRAN, which are on the long term designed to replace the "old" package adehabitat: * adehabitatMA: functions to perform spatial operations (morphology, buffer, etc.) * adehabitatHS: functions for the analysis of habitat selection by wildlife * adehabitatHR: functions for home range estimation of animals * adehabitatLT: functions for

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>

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???

Dear all, I'm trying to get a Brownian bridge kernel (kernelbb) for each combination of two consecutive animal locations (see commands below) and put them, with a loop, inside a list. It works well at the beginning but after 42 runs, it appears the following warning : >Error in seq.default(yli[1], yli[2], by = diff(xg[1:2])) :  >  invalid (to - from)/by in seq(.) I looked at the

Today I installed the newest R develepment branch R version 2.14.0 Under development (unstable) (2011-03-18 r54866) on FreeBSD 9.0-CURRENT (amd64). All seems fine so far. After that I updated my R packages with option 'checkBuilt=TRUE'. There are four packages (spatstat, pscl, adehabitatLT, adehabitatHR) which gives an error like this: Error in dyn.load(file, DLLpath = DLLpath, ...) :

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 I wonder if anybody can help, I am using the package adehabitatHR to estimate the potential distribution of a species using the command "domain" In the example given in the AdehabitatHS manual a map containing elevation information is loaded (class= spatial pixels data frame) as well as the GPS points of the animals being tracked, these are then plotted on each other and

Dear list members I am calculating kernel home-ranges and would like to visualize them with the function image(). The xy-values consist of longitude and latitude data. example:       x        y 36154.97 355143.0   R-code: xy<-hares[,c("x","y")] id<-hares[,"date"]   (ud1 <- kernelUD(xy, id)) ud2 <- getvolumeUD(ud1) image(ud2)   My problem is that the image

Dear all, I have uploaded to CRAN the version 1.7 of the package 'adehabitat'. Significant changes are listed below: * The Brownian bridge kernel estimation algorithm has been greatly improved. It now takes more than 80% less time than the previous version. A new function "liker" has also been added, which estimates the one of the two smoothing parameters of the bridge
