Calculate z-scores for each hexagon by sum of individual z scores

Usage

calculate_z_scores(land_hex, hex_id, stratum_id = NULL, quiet = FALSE)

Arguments

land_hex: (Spatial) Data frame. Land Cover data by hexagon. If non-spatial, will be converted to spatial sf data frame using the crs and coords arguments. Requires columns identifying the Hex ID as well as the Stratum ID (see hex_id and stratum_id respectively).
hex_id: Column. Identifies hexagon IDs (e.g., default hex_id).
stratum_id: Column. Identifies larger area (e.g., StudyAreaID or Province).
quiet: Logical. Whether to suppress progress messages.

Value

data frame
