Sorry, I just found this to be a common "problem" of tri.mesh: I had to "jitter" one of my first three coords in the point set:
x[2] <- x[2] + 0.01 Though, that does not seem to sound clean. Is there a better way? 2012/7/19 Erdal Karaca <[email protected]> > 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, "remove") : error in trmesh > > > tri <- tri.mesh(x, y, "strip") > Fehler in tri.mesh(x, y, "strip") : error in trmesh > Zusätzlich: Warnmeldung: > In hist.default(i, plot = FALSE, freq = TRUE, breaks = seq(0.5, : > argument 'freq' is not made use of > > > What could be wrong here? > [[alternative HTML version deleted]]
