Re: [R-sig-Geo] look for advice on handling 3D/4D trajectories in R

Hi Paedro, Might want to look into the mkde package ( https://cran.rstudio.com/web/packages/mkde/index.html) - it's designed to use 3d tracking data to estimate movement in 3 dimensions. Hope that helps, Mike On Fri, Nov 4, 2016 at 1:09 PM, Pedro C. Alvarez wrote: > Hi all, > > I am interested

[R-sig-Geo] look for advice on handling 3D/4D trajectories in R

Hi all, I am interested in handling 3D (lat, long, altitude) or even 4D (3D+time) aircraft trajectories in R. I am new to GIS (although not to R), then, I have been searching through r-project, R-sig-geo, the web ... and I've found and concluded that sp classes and some avalaible packages like

Re: [R-sig-Geo] Simple features now on CRAN

Super awesome, Edzer, and all who were involved! This represents a massive leap forward in compatibility and future-proofing for those of us working every day with spatial data in R. I'll jump in on testing and hopefully can contribute to push along things with raster-related processing as well.

[R-sig-Geo] Neighborhood matrix from poly2nb (spdep package)

Hi, I'm trying to extract the 'neighborhood matrix' from the poly2nb function. I can see the neighbors for each polygon, e.g. 1 has neighbors 2, 3, 5, 6. I try to convert this matrix into a data frame but get the error "cannot coerce class ""nb"" to a data.frame". Is there any way of doing this
