Hi,

When plotting the density estimation with DrawDensity3D-function (in
package VecStatGraphs3D) it often happens that the end product ie.
layers are not intact , see figure in the link:

Can we somehow effect on that an get intact layers?


That package appears to be using misc3d to draw the contours. misc3d::contour3d requires values in a 3-d grid, and will draw open contours if the contours hit the boundary.

I don't know how DrawDensity3D is producing the grid of values, but you'd likely have to modify it to use a bigger grid around the points, (so the density falls close to zero at the boundaries), or to artificially surround the density estimates with a layer of zero density values.
