3

ublkavgR(data, vars, domain = NULL, xyz = c("x", "y"),
  weights = NULL, factor = 2, minfrac = 1e-05, avg_method = 0,
  append_frac = FALSE, indims = c(1, 1, 1))

`data`	Data frame containing x, y, and, optionally z coordinates and one or more fields to average or assign by dominance.
`vars`	Character vecotr of variables to average or assign by dominance.
`domain`	Character vector for domain field to assign by dominance.
`xyz`	Character vector of coordinate field names.
`weights`	Charcater vector of weighting field name(s).If one field it is applied to all fields except `domain`.
`factor`	Numeric positive number: multiplicative factor to scale grid.
`minfrac`	Minimimum fraction of upscaled grid node that is represented by the input grid.
`avg_method`	Integer vector of averaging methods to use: 0 = arithmetic mean; 1 = geometric mean; 2 = harmonic mean; 3 = majority rules (for categorical variables)
`append_frac`	Scalar boolean: append fraction field to output.
`indims`	Numeric vector of grid dimensions for input grid.

There is currently an issue with the implimentation of the domain argument. It is supposed to produce a variable 0 to 1 in the output grid, which is the average of a domain indicator. It current gives wrong result and I am not sure if it is this implimentation of the Fortran program at fault.

Data frame of re-scaled grid.
