Full_Name: Michael R. Allen Version: 1.01 OS: linux redhat Submission from: (NULL) (149.149.32.46) Hello, Thought you might be interested. I tried to load the package tripack needed by the sgeostat package. After some careful searching, three packages were found which had the same error. Here is the output. Mike > library(acepack) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/usr/lib/R/library/acepack/...

This is not a bug in R. Please read the FAQs! You have got a version of tripack that has been compiled for R < 2.4.0. Please type update.packages(checkBuilt = TRUE) and try again.

Hello. I'd like to convert voronois object created by tripack to polygons to use them in GIS(Geographic Information Systems) software. I tried to create voronoi objects by using following code. > library(tripack) > x <- rnorm(10) > y <- rnorm(10) > plot(x,y) > v<-voronoi.mosaic(x,y) > plot(v) But from here, I could not create po...

Hi, I created before a bug-entry: http://bugs.r-project.org/cgi-bin/R/incoming?id=3D9390;expression=3Derkan;u= ser=3Dguest here is an addition which I can not add because the interface won't let me: more info: tripack_1.2-10.zip: file version of tripack.dll: 2.10.50418.0 before installing tripack, I installed following packages: ncf_1.0-8.zip spdep_0.3-32.zip original report: Hi, just installed R 2.4.0 (before there was running 2.2.0). when loading the library ("library(tripack)"), there appears...

...rk and when I tried to re-install them through `R INSTALL package.tar.gz'', some just fail and give similar error messages. My `ts'' works, but it is of the old original version, and I don''t dare to check if it stops working after re-installation.

Okay, been working with tripack, seems the most mature package for this. Got it to work well with their test data set - data(tritest). When i tried random numbers to explore further, i am getting some results that don't reconcile. example run this: library(tripack) y <- runif(100) x <- runif(100) vm <- voronoi....

I am trying to triangulate a point set as follows: > head(cbind(x,y)) x y [1,] -78.1444 -60.4424 [2,] -78.1444 -58.4424 [3,] -78.1444 -56.4424 [4,] -78.1444 -54.4424 [5,] -76.1444 -60.4424 [6,] -76.1444 -58.4424 > length(x) [1] 5000 > tri <- tri.mesh(x, y) Fehler in tri.mesh(x, y) : error in trmesh > tri <- tri.mesh(x, y, "remove") Fehler in tri.mesh(x, y,

Dear all; First of all, this is probably a more conceptual question than a R-related one, but still want to give it a try. When working with the interpolation function "interp" from the package akima and the triangulation function "tri.mesh" from package tripack I've got NA's for the interpolation and "error" for the triangulation. The data is arranged in a regular grid as opposed to what the help page for interp says but I think this is an interesting problem because I found this code on the web as part of an stats course (and it is not...

Hi all, I am running R 2.5.0 under Windows XP Media Center Edition. Here's a problem that's been stumping me for a few days now, and I can't find anything useful in the archives. I am using voronoi.mosaic (tripack package) to create proximity polygons for a study of vegetation competition and dynamics. The points lists are read in from a file for each plot, then 8 duplicates are translated around the edges of the plot (Toroidal edge correction). This is completed using the torus(...) function that I w...

Dear UseRs, I would like to know which function is the most efficient in finding convex hull of points in 3(or 2)-dimensional case? Functions for finding convex hull is the following: convex.hull (tripack), chull (grDevices), in.chull (sgeostat), convhulln (geometry), convexhull.xy (spatstat), calcConvexHull (PBSmapping). I also would like to know if there is a function that can be used for finding convex hull in multi-dimensional case, that is more than 3- dimension. Thank you in advance.

There's Renka's STRIPACK, and TRIPACK, respectively, ACM TOMS Algorithms 772 and 751, and there's the R package "deldir" which does the Delaunay for a plane, but does anyone have or know of the tessellation in R for a sphere? Also, is there a standard indexing scheme for Delaunay facets, and perhaps of edges...

...atticeExtra) like the ones attached, and with the following commands: xy=list(x=x2$X, y=x2$Y) xy$street_cle <- x2$street_cle tileplot(street_cle~ x*y, xy) But this is a trellis. Is it possible to be converted to a shapefile or image so I can plot it using spplot. I tried the following under tripack: > tritest.vm <- voronoi.mosaic(x2$X,x2$Y) > x2.vm <- voronoi.mosaic(x2$X,x2$Y) > plot(x2.vm) > x2.vp <- voronoi.polygons(x2.vm) > plot(x2.vp) The mosaic is fine but when I made it to voronoi polygon, it gives me a weird plot just like the ones attached in this message....

...do the tesselation so that the polygon size for each tree depends on the size of the subject tree, and the size of its neighbors. So, the location of the bisection between two trees would not necessarily be at the midpoint, but determined by the tree sizes. I have looked through the options in tripack and deldir-packages, but editing the functions in those packages is beyond my skills. Thanks, Tuomas
