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 convert the kas...

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 by 1 using the following, but get stuck after that: (file1 <- paste(system.file(package = "adehabitat"), "ascfiles/annheat.asc&q...

Dear all, I have just uploaded to CRAN the version 1.3 of the package 'adehabitat'. Significant changes are listed below: - Several functions allowing the conversion from and to classes of the package sp have been added. Maps of class "asc", "kasc", "area", as well as radio-monitoring of class "traj" can now be converted to the spatial classes available in sp. - The function buffer.line() allows to compute buffer around a line - The function distfacmap() converts one factor map into a set of maps giving the...

...methods allowing the analysis of animals movements have been added, including the first passage time (function fpt()), a rediscretization algorithm (redisltraj()), and an interactive graphic window for dynamic analysis (trajdyn()) * A function for interactive exploration of maps of class "kasc" has been added (explore.kasc) * Scott Fortmann-Roe (Univ. Berkeley) programmed a better algorithm for Nearest neighbour Convex hull home range estimation. * The function kasc2spixdf() have been updated Happy testing, Cl?ment CALENGE -- Cl?ment CALENGE Laboratoire de Biom?trie et Biol...

...nctions allow to simulate common models of trajects: the correlated random walk (simm.crw), the brownian motion (simm.brown), the arithmetic brownian motion (simm.mba), the Ornstein Uhlenbeck process (simm.mou), the brownian bridge (simm.bb) and the Levy process (simm.levy). * The function explore.kasc() provides a Tk interface for the exploration of a multi-layer raster map of class "kasc" * A partitioning algorithm (still under research) is also available to partition a traject into segments with homogeneous properties (see the help page of modpartltraj) * The bugs in redisltraj and...

...hbour 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). Some arguments of the graphical functions have also been changed (kernel, image.kasc, scatter.enfa). Finally, some minor bugs have been corrected. Note that the package now need that the packages ade4 and gpclib are installed. Questions, comments and suggestions are greatly appreciated.

..." is now named "co", and corresponds to the scores of habitat variables in the enfa (the squared norm of this vector is equal to 1 for the identity metric). As previously, the component "li" stores the scores of the resource units in the ENFA. - The function df2kasc now accept objects of class "kasc" with one column. - That's all, thanks for reading !
