The theoretical best basis is usually known for a simulated problem. Augment this information into the data object allows for evaluating the performance of optimisation against the theory.

bind_theoretical(dt, matrix, index, raw_data)

Arguments

dt

a data object collected by the projection pursuit guided tour optimisation in the tourr package

matrix

a matrix of the theoretical basis

index

the index function used to calculate the index value

raw_data

a tibble of the original data used to calculate the index value

Value

a tibble object containing both the searched and theoretical best bases
