A ggproto for drawing interpolation path

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

add_interp(
  dt,
  interp_size = 1.5,
  interp_alpha = NULL,
  interp_color = NULL,
  interp_group = NULL,
  ...
)

Arguments

interp_size

numeric; the size of the interpolation path

interp_alpha

numeric; the alpha of the interpolation path

interp_color

the variable to be coloured by

interp_group

the variable to label different interpolation path

...

other aesthetics inherent from explore_space_pca()
