Functions in DiceView (2.2-0)

One Dimensional Root (Zero) Finding

One Dimensional Multiple Roots (Zero) Finding

Extract points of mesh which belong to the mesh triangulation (may not contain all points)

points_out.mesh

Extract points of mesh which do not belong to the mesh triangulation (may not contain all points)

Multi Dimensional Multiple Roots (Zero) Finding, sampled by a mesh

Title Multi-local optimization wrapper for optim, using (possibly parallel) multistart.

Minimal distance between one point to many points

Plot a three dimensional mesh

Plot a one dimensional mesh

Plot a two dimensional mesh

sectionview.function

Plot a section view of a prediction model or function, including design points if available.

sectionview3d.function

Plot a contour view of a prediction model or function, including design points if available.

Test if points are in a hull

Generalize expand.grid() for multi-columns data. Build all combinations of lines from X1 and X2. Each line may hold multiple columns.

This is a simple copy of the Branin-Hoo 2-dimensional test function, as provided in DiceKriging package. The Branin-Hoo function is defined here over [0,1] x [0,1], instead of [-5,0] x [10,15] as usual. It has 3 global minima : x1 = c(0.9616520, 0.15); x2 = c(0.1238946, 0.8166644); x3 = c(0.5427730, 0.15)

contourview.function

Plot a contour view of a prediction model or function, including design points if available.

Checks if some points belong to a given mesh

Memoize.function

Memoize a function

Checks if some point belongs to a given mesh

Search excursion set of nD function, sampled by a mesh

Vectorize.function

Vectorize a multidimensional Function

Apply Functions Over Array Margins, using custom vectorization (possibly using parallel)
