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?
