[R-sig-Geo] one-dimensional spatial point process

2011-10-11 Thread Matilde Karakachoff
Hello, I'm looking for some simple techniques of exploratory data analysis for a one-dimensional spatial point process. For example I would test the CSR of some (few) points in a line of length 5000 against the hp. that they cluster in one or two places of the line. Do you think that there

Hello. I don't know whether this is correct answer to your question, how about using nearest neighbor analysis for point pattern? This method is written in Boots, B. N. and Getis, A. (1988): Point Pattern Analysis, Scientific Geography Series, SAGE PUBLICATIONS, 45-56. I think this

While open source gis is appealing most jobs still require introductory employees to use arcgis products. I'd stay away from anything else if you want your students to thank you latter. Steve On Oct 11, 2011 4:33 PM, Jonathan Greenberg j...@illinois.edu wrote: R-sig-geo'ers: I wanted to take

Hi all, I've got a georeferenced grid with elevation data (height of land, depth below sea level). I have loaded it into R in various formats. I would like to coarsen it to match other environmental datasets for species distribution modeling purposes, but I feel that the coarsened grid

Since the format is raw binary it would be easy enough to read the raw values with ?readBin and construct a Spatial object from that. If there is sufficient metadata with the files it might already be recognized by a GDAL, and if you are lucky in turn by your build of rgdal (I've not checked the
