Dear mailing list members, I am currently working with the Geolife dataset from Microsoft Asia (About 17.000 trajectories, mostly Beijing area). I want to analyze route usage (for now only basic descriptives: how many trajectories use one same route, hours of the day in which those routes are more popular). I want to ask you if there is any specific package I should look at (so far I have seen packages that only built a dataframe and make some basic plots). Any ideas? Best regards, EV

I suggest you peruse through the Spatial task view ( http://cran.r-project.org/web/views/Spatial.html). Package `sp` lays down the ground work (spatial classes like SpatialLines, SpatialPoints, SpatialPolygons...), and there's a plethora of packages to tinker with this or that.

Hi It is difficult to tell from your email which packages you have been exploring so far. Perhaps the trajectories package? Did you have a look at the adehabitatLT package? See e.g. http://cran.r-project.org/web/packages/adehabitatLT/vignettes/adehabitatLT.pdf.

when you are in the top directory of the geolife data set, start R, then library(trajectories) demo(geolife) will read part of the data set. Copy the script [1] to this directory, and start editing. Read the package vignettes to see what the package can do for you. Don't forget to report back to the list what the package can not do for you, or consider contributing back to the package! With best regards, [1] found in the demo directory of the package, or alternatively on https://github.com/edzer/trajectories/blob/master/demo/geolife.R
