add_search

This is a wrapper function used by <code>explore_space_pca()</code> and
should be be called directly by the user

Diagnostic plots for optimisation, with a focus on projection pursuit. These show paths the optimiser
takes in the high-dimensional space in multiple ways: by reducing the dimension using principal component analysis, and
also using the tour to show the path on the high-dimensional space. Several botanical colour palettes are included, reflecting the
name of the package. A paper describing the methodology can be found at <https://journal.r-project.org/articles/RJ-2021-105/index.html>.
