Yesterday Jay Call drew to my attention the fact that the triMat() function was giving wrong answers in some instances. Wrong answers occur if the union of three contiguous Delaunay triangles happens to constitute another triangle. This latter triangle appeared in the list of triangles produced by triMat() but is *not* itself a Delaunay triangle (and hence should not appear in the list).
I have swatted this bug (at least I think/hope that I have!) and have uploaded a revised version of deldir (version 0.1-14) to CRAN. The revision contains other amendments and innovations in addition to this bug fix.
If you have in the past used triMat(), you should check your results from that usage against those produced by the triMat() function from the revised version.
Sorry 'bout that. cheers, Rolf Turner -- Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276 ______________________________________________ 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.
