Usage

calculate_nei(from = NULL, locs = NULL, locs_id = "site_id", geom = FALSE, ...)

Arguments

from: SpatVector(1). Output of process_nei().
locs: sf/SpatVector. Locations at NEI values are joined.
locs_id: character(1). Unique site identifier column name. Unused but kept for compatibility.
geom: FALSE/"sf"/"terra".. Should the function return with geometry? Default is FALSE, options with geometry are "sf" or "terra". The coordinate reference system of the sf or SpatVector is that of from.

Examples

## NOTE: Example is wrapped in `\dontrun{}` as function requires a large
##       amount of data which is not included in the package.
if (FALSE) { # \dontrun{
loc <- data.frame(id = "001", lon = -78.90, lat = 35.97)
calculate_nei(
  from = nei, # derived from process_nei example
  locs = loc,
  locs_id = "id"
)
} # }
