Merges a list of delineated polygons into a single spatial object

For a given list of shapefile filepaths, this function will load and combine the shapefiles into a single shapefile object. Each polygon will retain the original attributes assigned to it.

merge_delineated_polygons(shp_paths, message = TRUE)

Arguments

shp_paths	a list of polygons
message	should progress messages be displayed? Default is TRUE

Value

A SpatialPolygonsDataFrame with the identifier column ID

Examples

# Merge the example polygons within the package
library(polyCheck)
polygons <- list_polygons(system.file("extdata/polygons", package = "polyCheck"))
polygons_all <- merge_delineated_polygons(polygons)
