zeroInflate: zeroInflate or blanking

In BradHubley/SpatialHub: Survey Design and Spatial Analysis of Fisheries Data

zeroInflate or blanking

Description

incorporates blanking distance by including zeros spaced eqully at the average nearest nieghbour distance, default blanking distance is the nearest neighbour distance of the most isolated point. Called by interpolation.

Usage

zeroInflate(
  xyz,
  blank.dist,
  scale = 20,
  corners = NULL,
  aspr = 1,
  type = 2,
  eff = 0,
  type.scaler = 1
)

Arguments

xyz	= data.frame of points containing X and Y coordinates
blank.dist	= distance at which zeros are inserted into the data set, defaults to the largest nearest neighbour distance i.e. the distance to the most isolated point in the data
scale	= how far beyond the range of the data are points inserted
corners	= undocumented
aspr	= aspect ratio for for creating square grid
type	= how spaced out the zeros are, 1 = avg. nearest neighbour distance, 2 = blanking distance
eff	= what data is inserted, intended for zeros
type.scaler	= undocumented
