I will add a "[.tile.list" method in the next release of deldir so that the appropriate attributes are preserved. This won't happen for a month or so though; I have some other pressures on me at the moment. cheers, Rolf Turner On 15/01/15 04:52, Raphael Päbst wrote: Thanks Boris! I know th

Thanks Boris! I know that I am just leaving out some tiles in the plot, but I specifically want to drop those tiles for the plot and not calculate a tesselation without these points. So I'll go with this solution and hope it makes sense in the end. Thanks again! Raphael On 1/14/15, Boris Steipe

2015-01-14 Thread Raphael Päbst
Hello everybody! I feel very stupid right now but suspect it has something to do with tiredness. I am trying to drop the last couple of Elements from a list and this doesn't work as expected. My code looks something like this: del <- deldir(x, y) tl <- tile.list(del) plot(tl) Now, I only want to
