Hi, Recently, I used igraph with spatial objects.
Once you have the coordinates of the nodes composing an edge, you can transform it into a spatiallines object with this function : makeLineFromCoords <- function(coords, i) { Sl1 = Line(coords) S1 = Lines(list(Sl1), ID=as.character(i)) Sl = SpatialLines(list(S1)) return(Sl) } For all the routing stuff within R, this resource by B. Rowlingson is quite inspiring : http://rstudio-pubs-static.s3.amazonaws.com/1572_7599552b60454033a0d5c5e6d2e34ffb.html best, Mathieu 2016-02-22 9:30 GMT+01:00 Michael Sumner <mdsum...@gmail.com>: > On Mon, 22 Feb 2016 at 19:13 Luca Candeloro <luca.candel...@gmail.com> > wrote: > > > Dear all, > > plotting graphs with given vertex coordinates is possible inside igraph > > plot function. > > I would like to transform vilsualized edges into SpatialLinesDataFrame, > so > > that they could be exported in .shp file... > > Any suggestion? > > > > Can you please provide a working igraph example that we can start with? > > Do you want coordinates as seen in a particular plot, or can it be more > arbitrary? > > Cheers, Mike. > > > > > thanks in advance, > > Luca > > > > [[alternative HTML version deleted]] > > > > _______________________________________________ > > R-sig-Geo mailing list > > R-sig-Geo@r-project.org > > https://stat.ethz.ch/mailman/listinfo/r-sig-geo > > > -- > Dr. Michael Sumner > Software and Database Engineer > Australian Antarctic Division > 203 Channel Highway > Kingston Tasmania 7050 Australia > > [[alternative HTML version deleted]] > > _______________________________________________ > R-sig-Geo mailing list > R-sig-Geo@r-project.org > https://stat.ethz.ch/mailman/listinfo/r-sig-geo > [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
