Hello to all, I have struggling with R for at least a weak and I guess I do really need your help figuring this out.
I have to work with a large data set (thousands of points) and to create figures that are small and good looking for publications. You can probably suggest me a slick a working way to approach this problem. I would really appreciate. Let say we start with: data(akima) dimgrid=50 ak.li=interp(akima$x, akima$y, akima$z, xo=seq(min(akima$x), max(akima$x), length = dimgrid),yo=seq(min(akima$y), max(akima$y), length = dimgrid),linear = TRUE, extrap=FALSE, duplicate = "mean") # Now I have the regular grid. cLines = contourLines(x = ak.li$x, y = ak.li$y, z = ak.li$z, nlevels = 7) # Now I have the contours... That is from that point on that I cannot find a solution. I tough of selecting all the image data and converting it a specific class value, but then I still get stuck into the same issue I dont know how to convert those pixel into polygons. # ... I do need guidance... Thanks a lot! Seb _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
