Dear all,
I have just uploaded to CRAN a new version of adehabitatLT and
adehabitatHR.
Significant changes in adehabitatLT are listed below:
* The residence time method of Barraquand and Benhamou (2008) is now
implemented in the function residenceTime.
* The segmentation method of Lavielle
Hello,
Having searched around on some related posts I have yet to figure this one
out. While trying to grab the spatial information of a raster I turned to
the readOGR function.
myprj-readOGR(dsn=c:/temp/,layer=RasterDat)
but got an error:
#Error in ogrInfo(dsn = dsn, layer = layer,
The first one is easy, probably raster data, not vector and is named
RadarDat not RasterDat:
myprj-readOGR(dsn=c:/temp/,layer=RasterDat)
library(rgdal)
myraster - readGDAL(c:/temp/RadarDat.asc)
For this one, you don't need system.file()
Hi Michael,
Thanks for pointing out my blunders, it never pays to work late as evidenced
by such simple mistakes. That is not to say I didn't learn anything from
your response, I certainly did. Part of why I was trying to get at the
spatial reference information in my first post was because it
Hi List,
I have 1227 data plots regularly sampled in a grid
of 1 x 1 Km in which species richness and abundance of 682 vascular plant
species have been recorded.
I constructed also a database of environmental
variables with GIS. My first goal was to compute a GLS model to explain species
