get_centroid_weighted: Get weighted centroid of hypervolume or hypervolume list.

In hypervolume: High Dimensional Geometry, Set Operations, Projection, and Inference Using Kernel Density Estimation, Support Vector Machines, and Convex Hulls

Description

Returns the column weighted mean of the random points in each hypervolume. Useful for hypervolumes generated with hypervolume_n_occupancy or hypervolume_n_occupancy_test.

Usage

get_centroid_weighted(hv)

Arguments

hv	A Hypervolume or HypervolumeList object.

Value

Either a vector or a matrix of column of centroid values along each axis.

Examples

data(penguins,package='palmerpenguins')

penguins_no_na_split = split(penguins_no_na,

hv_list = lapply(penguins_no_na_split, function(x) 
  hypervolume_gaussian(x[, c("bill_length_mm","bill_depth_mm","flipper_length_mm")],
  samples.per.point=100))

hv_list <- hypervolume_join(hv_list)
hv_occupancy <- hypervolume_n_occupancy(hv_list)

# unweighted centroids
