%description
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/archive/2021/RJ-2021-105/index.html>.
