The MabLab at the University of Florida's Fort Lauderdale Research and Education Center (Davie, FL) is looking to fill an immediate opening for the position of a Biological Scientist. We are looking for an enthusiastic, highly motivated and responsible individual to join an exciting research team focused on spatial ecology, from fine-scale movement and habitat selection to range dynamics.

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

We'd like to announce the initial CRAN release of 'rpostgis' (v1.0.0), which facilitates transfer between PostGIS "Geometry" objects (stored in PostgreSQL databases) and R spatial objects. The package also contains a variety of convenience functions which are supplemental to the excellent 'RPostgreSQL' package for interfacing with a PostgreSQL/PostGIS database. To

Hey all, I've run into a few problems running first passage time analysis. I'm hoping someone might be able to help me sort this out. I'm fine up to the point of creating the ltraj object from a dataset. /test<-read.table("~/Desktop/R_Directory/test.txt",header=TRUE) attach(test) library(adehabitatLT) xy<-test[,c("x","y")]

Dear R list, I have a package downloaded and looked up a function in there. Now I find that it uses C code (.C call) to do part of its job. However, when I wanted to look that part up by using getAnywhere() I was told that no object of that name could be found. Then I tried typing C.(" funct.name") which only caused R to crash. Is there any way to look up the function? I'm not

Hi all, here's a proposal for a SoC project on wildlife movement patterns analysis. A MSc student is available to anwser the call, of course. The idea has already been briefly discussed with the mantainer of the adehabitat package and the AniMov project community. Short description Develop some add-on functions to use the adehabitat package to perform basic movement ecology analysis, in

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 just uploaded to CRAN the version 1.4 of the package 'adehabitat'. Significant changes are listed below: - The eigenanalysis of selection ratios (Calenge and Dufour, 2006, Ecology) can now be performed using the function eisera(). It can be used for the analysis of habitat selection when habitat can be considered to consist of several habitat types (e.g.

Hi. I am running the as.ltraj () function in adehabitat (v 1.4 under R 2.2.1) but can't seem to correctly specify the burst argument. i.e., the ltraj object returned consists of only one component, when in fact my data consist of more than one burst of reloctions per animal. i've set up the data (xy, date, id, burst) in list form following the example given in ?as.ltraj. to simplify,

Dear list, I have a table with entries for 20 animals - x and y coordinates to analyze movement with the package adehabitat. The package does all the necessary analyses, but I need to create an object of class ltraj for each animal first. For this kind of object I need to define xy coordinates, id, and few other things for each individual. Now I don't want to run a code 20 times

Dear all, I have just uploaded to CRAN the version 1.6 of the package 'adehabitat'. Significant changes are listed below: * The package has been reorganized into four parts (see ?adehabitat-package for a description): (i) management of raster maps, (ii) habitat selection / ecological niche analysis, (iii) home range analysis, and (iv) analysis of animals trajects. The package contains

Hello list, I'm just getting started with using R - I have been trying over the past day or so to work out a method for generating voronoi polygons for PostGIS using SQL. I was able to put together a procedure which works relatively well, but is somewhat inefficient. Someone on the PostGIS list pointed me to the deldir() function in R, for which I can export a text file with x/y coordinates

Hi. I''m announcing a Rails Engine for presenting maps based on your own data, either rendered by Mapserver, or pulled directly out of geometric database tables stored by PostGIS. There''s a demo here: http://ivygis.mgxkernel.com:3000/canada which shows a tiled, draggable version of a Mapserver demo map, with mouse-sensitive park polygons and railroads (SVG in Firefox 1.5+,

Just wanted to post this in case someone else was faced with the same problem. It''s database-specific code, worse, it''s specific to a particular * version* of a particular *extension* to a particular database, wires in SQL, and uses eval on a string of data from the database! So, you know, I''m getting coal in my stocking from DHH this year. I can deal. (After 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"),
