adehabitat version 1.8
Dear all, I have uploaded to CRAN the version 1.8 of the package 'adehabitat'. Significant changes are listed below: * getverticeshr now relies on the function contourLines(), and returns smoother estimates of the kernel home range (see the help page). * the new function kernelkc (and related functions) now allows the estimation of the utilization distribution in space and time of

How can I use Adehabitat to obtain an .asc object with the predicted values of a niche model?
Dear all, I'm using the package adehabitat in R to import several .asc files (=matrix), and also create a kasc object (=dataframe) with all of them. The main idea is to use this kasc object to map the predicted values of climate-matching model for an overall area. However, I don't know how to proceed: Do I have to project the model (already stored in R) onto the kasc object directly, or

[SoC 2009] will R Foundation participate? project proposal: fractal analysis
Hello R developers, I know it is still a bit early to talk about Summer of Code, but I wish to know what are, approximately, plans for this year. Last year I applied as a student under OSGeo with a QGIS-R project and had a very positive experience [0], therefore I plan to participate again. I found an interesting hint [1], about implementing fractal analysis in R, and a would-be mentor has

adehabitat raster import
Hello all, I'm new to adehabitat and am having trouble getting my ascii files into the r. I have 45 environmental data layers that are all stored in a folder as ascii files. Is there an easy way to pull in all 45 of my data layers into a kasc dataframe. I'm not new to r or multivariate modeling, but the documentation seems confusing. I've experimented with bringing a few of them in 1

Adehabitat package question - trying to generate animal home ranges
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

New package: adehabitat
Dear all, I have just uploaded a package to CRAN a new package called 'adehabitat'. This package is intended for ecologists who want to analyse the use of space by animals. Many functions currently used in this field are available to highlight habitat selection by animals (selection ratios, ENFA, habitat suitability maps with the algorithm DOMAIN or Resource Selection Functions) or to

adehabitat functions
Is there a way to just build a madifa function in adehabitat just using a .csv file with presences and the corresponding environmental data? I'm trying to model the species distribution of a species using 45 environmental grids and r crashes after loading just 5 of them. I'd like to develop the function and then predict it using a line by line predict function, but can't figure out if

Calculating home ranges using mcp in adehabitat
Hello, I've been trying to calculate home range sizes (for Icelandic geese!) using minimum convex polygons with the adehabitat package. I've tried to use the R code shown by demo(homerange) in adehabitat and when that didn't work I've fiddled around with it but to no avail...Below is the output of the demo that I've attempted to follow, followed by a subset of my data (for one

adehabitat version 1.2
Dear all, I have just uploaded to CRAN the version 1.2 of the package 'adehabitat'. This package now contains new functions for the estimation of home ranges (Nearest neighbour convex hull, brownian bridge approach for kernel estimation), estimation of schoener's ratio. This package now allows a better management of objects of class "area" (see plot.area, perarea, ararea).
