find_jumps: Find dispersal jumps

In nbelouard/slfjumps: Identify jump dispersal in biological invasions

Find dispersal jumps

Description

Find dispersal jumps after having applied find_thresholds(). Prune points selected due to sector limits and secondary diffusion.

Usage

find_jumps(
  grid_data = grid_data,
  potJumps = potJumps,
  gap_size = 15,
  crs = 4326
)

Arguments

potJumps	A data frame of potential jumps to be refined, resulting from find_thresholds()
gap_size	Distance between the invasion front and the positive point necessary for it to be considered a jump, in kilometers (default: 15)
crs	Coordinate system used for spatial layers (default: 4326)
dataset	A data frame of unique points to be processed, i.e., the initial grid_data table

Value

Two data frames: Jumps containing the list of jumps, and potSecDiff containing potential secondary diffusion to be processed using find_secDiff()

Examples

jumps <- find_jumps(dataset)
