Binary logical operations (2)
Binary logical operations (binary predicate functions) describe the topological relationship between a pair of simple features.
Applied to two sf
objects, they return:
- either a sparse matrix (
sgbp
class: sparse geometry binary predicate), - or a dense matrix.
## Sparse geometry binary predicate list of length 3, where the predicate
## was `intersects'
## 1: 1, 3
## 2: 2, 3
## 3: 3
## [1] "sgbp" "list"
## List of 3
## $ : int [1:2] 1 3
## $ : int [1:2] 2 3
## $ : int 3
