Manual Tours, Manual Control of Dynamic Projections of Numeric
Generates the path for manual tours
['Cook' & 'Buja' (1997) <10.2307>]. Tours are generally available in the
'tourr' package ['Wickham' 'et' 'al.' (2011) <10.18637>].
The grand tour is an algorithm that shows all possible projections given sufficient time.
Guided uses projection pursuit to steer the tour towards interesting projections.
The 'spinifex' package implements manual control, where the contribution of a selected variable
can be adjusted between -1 to 1, to examine the sensitivity of structure in the data
to that variable.
The result is an animation where the variable is toured into and out of the projection
completely, which can be rendered using the 'gganimate' and 'plotly' packages.10.18637>10.2307>
