Determine the concentrations within the highest focal cells for the current iteration

Description

Determine the concentrations within the highest focal cells for the current iteration.

Usage

concentration_per_candidate_cell(
  candidate_cells,
  dff,
  value,
  size,
  points,
  cache,

Arguments

candidate_cells	data.frame containing cell ids with focal values selected for refinement in the current iteration.
dff	data.frame with all observations
value	column name in 'dff' to find concentrations for.
size	size of cell in meters.
