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

blanking(
  surv.dat,
  blank.dist,
  aspr,
  type = 1,
  eff = 0,
  scale = 0.5,
  type.scaler = 0.5
)

Arguments

`surv.dat`	= 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
`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
`scale`	= how far beyond the range of the data are points inserted
`type.scaler`	= undocumented
