tongfen_estimate {tongfen} | R Documentation |
Estimate variable values for custom geography
Description
Estimates data from source geometry onto target geometry using area-weighted interpolation. The metadata specifies how data should be aggregated, "additive" data like population counts are summed up proportionally to the area of the intersection, "averages" need further additive "parent" count variables to estimate weighted averages.
Usage
tongfen_estimate(target, source, meta, na.rm = FALSE)
Arguments
target |
custom geography to estimate values for |
source |
input geography with values |
meta |
metadata for variable aggregation, see 'meta_for_additive_variables' and 'meta_for_ca_census_vectors' for more information on how to construct metadata. |
na.rm |
remove NA values when aggregating, default is FALSE |
Value
'target' with estimated quantities from 'source' as specified by 'meta'
