MRG (version 0.3.21)

MRGpostProcess: Make some final adjustments to the multiresolution grids

Description

Make some final adjustments to the multiresolution grids

Usage

MRGpostProcess(himg, vars, remCols = TRUE, rounding = "varying")

Value

The function will return a post-processed multi-resolution grid with non-confidential gridded data. See multiResGrid for more information.

Arguments

himg

A multi-resolution grid, typically resulting from a call to multiResGrid

vars

Variable(s) of interest that should be aggregated (necessary when ifg is used for individual farm specific anonymization rules)

remCols

Logical; Should intermediate columns be removed? Can be set to FALSE for further analyses. Temporary columns will not be removed if their names partly match the variable names of vars

rounding

either logical (FALSE) or an integer indicating the number of decimal places to be used. Negative values are allowed (such as the default value rounding to the closest 10). See also the details for digits in round.

Details

The postprocessing function is normally called directly from multiResGrid. However, it might be useful to check the values of the grid cells that will be suppressed, and the values before rounding. In that case multiResGrid can be called with the argument postProcess = FALSE, and the post processing be done separately.

Examples

# \donttest{
library(sf)

# These are SYNTHETIC agricultural FSS data 
data(ifs_dk) # Census data
# Create spatial data
ifg = fssgeo(ifs_dk, locAdj = "LL")

# Set the base resolutions, and create a hierarchical list with gridded data
ress = 1000*2^(1:7)
ifl = gridData(ifg, "UAA", res = ress)
himg = multiResGrid(ifl, ifg = ifg, var = "UAA", weight = "EXT_CORE", postProcess = FALSE)
himgp = MRGpostProcess(himg, var = "UAA")

# Confidential grid cells, being suppressed in postProcessing
himg[himg$confidential,]
 # }
