For `t = delaunay(cbind(x, y))`

, where `(x, y)`

is a 2D set of
points, `tsearch(x, y, t, xi, yi)`

finds the index in `t`

containing the points `(xi, yi)`

. For points outside the convex hull
the index is `NA`

.

1 |

`x` |
X-coordinates of triangluation points |

`y` |
Y-coordinates of triangluation points |

`t` |
Triangulation, e.g. produced by |

`xi` |
X-coordinates of points to test |

`yi` |
Y-coordinates of points to test |

`bary` |
If |

If `bary`

is `FALSE`

, the index in `t`

containing
the points `(xi, yi)`

. For points outside the convex hull the index
is `NA`

. If `bary`

is `TRUE`

, a list containing:

`list("idx")` |
the index in |

`list("p")` |
a 3-column matrix containing the barycentric coordinates with respect to the enclosing triangle of each point code(xi, yi). |
