`spatial_buffer_vfold_cv()` should handle `repeats` better #119

Closed mikemahoney218 closed 2 years ago

See #115

spatial_buffer_vfold_cv() can be deterministic (if v is equal to nrow(data), or NULL, or Inf) and we'd probably want to error there as well (although, that's starting to get into the realm of "if you found this edge case, you were doing something weird on purpose")

library(spatialsample)

spatial_buffer_vfold_cv(
  boston_canopy, 
  v = 2, 
  buffer = 1, 
  radius = NULL, 
  repeats = 2
)
