Dear forum, I have a number of random point in a polygon. I would like to find those points lying on the same lines. Is there an R function to find alignments in points (something like this: https://en.wikipedia.org/wiki/Alignments_of_random_points)? And is it possible to do the same thing but changing the width of lines?
If it could be useful, I attached an example of R code that I'm using. Thank's in advance, DF CODE: library(sp) poly<-matrix(c(16,17,25,22,16,58,55,55,61,58),ncol=2,nrow=5) > poly [,1] [,2] [1,] 16 58 [2,] 17 55 [3,] 25 55 [4,] 22 61 [5,] 16 58 p=Polygon(poly) ps=Polygons(list(p),1) sps=SpatialPolygons(list(ps)) p.rd=spsample(sps,n=150,"random") plot(sps) points(p.rd,pch=16, col='blue',cex=0.3) [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
