Combine Predictor Data from Multiple sf Objects

This function merges predictor variables from multiple sf objects into a single sf object. It preserves the geometry from the first input and joins columns from the other sf objects using a common key (h3_address or ID).

Usage

h3sdm_predictors(...)

Arguments

...

Two or more sf objects containing predictor variables. The first object must contain the geometry to preserve. All objects must share a common key column (h3_address or ID).

Value

An sf object containing the geometry of the first input and all predictor columns from all provided sf objects.

Details

The function uses a left join based on the h3_address column if present, otherwise it falls back to ID. Geometries from the right-hand side sf objects are dropped to avoid conflicts, and the final geometry is cast to MULTIPOLYGON.

Examples

if (FALSE) { # \dontrun{
# Combine sf objects with different predictor types into one
combined <- h3sdm_predictors(num_sf, cat_sf, it_sf)
head(combined)
} # }
