A function to create a list of owin objects from a SpatialPolygonsDataFrame
# S3 method for SpatialPolygonsDataFrame
as.owinlist(obj, dmin = 0, check = TRUE, subset = rep(TRUE, length(obj)), ...)a SpatialPolygonsDataFrame object
purpose is to simplify the SpatialPolygons. A numeric value giving the smallest permissible length of an edge. See ? simplify.owin
whether or not to use spatstat functions to check the validity of SpatialPolygons objects
logical vector. Subset of regions to extract and conver to owin objects. By default, all regions are extracted.
additional arguments
a list of owin objects corresponding to the constituent Polygons objects
