timeSequence: Time each index evaluation for projections in the tour path.

In spinebil: Investigating New Projection Pursuit Index Functions

Description

Index evaluation timing may depend on the data distribution, we evaluate the computing time for a set of different projections to get an overview of the distribution of computing times.

Usage

timeSequence(d, t, idx, pmax)

Arguments

d	Input data in matrix format
t	List of projection matrices (e.g. interpolated tour path)
idx	Index function
pmax	Maximum number of projections to evaluate (cut t if longer than pmax)

Value

numeric vector containing all distances

Examples

d <- spiralData(4, 1000)
t <- purrr::rerun(10, tourr::basis_random(4))
idx <- scagIndex("Skinny")
timeSequence(d, t, idx, 10)
