 This is especially true for *vector* operations: Section \@ref(vector-attribute-manipulation) on vector attribute manipulation provides the basis for understanding its spatial counterpart, namely spatial subsetting (covered in Section \@ref(spatial-subsetting)).
 Spatial joining (Section \@ref(spatial-joining)) and aggregation (Section \@ref(spatial-aggr)) also have non-spatial counterparts, covered in the previous chapter.

+Spatial operations differ from non-spatial operations in a number of ways, however:
 Spatial joins, for example, can be done in a number of ways --- including matching entities that intersect with or are within a certain distance of the target dataset --- while the attribution joins discussed in Section \@ref(vector-attribute-joining) in the previous chapter can only be done in one way (except when using fuzzy joins, as described in the documentation of the [**fuzzyjoin**](https://cran.r-project.org/package=fuzzyjoin) package).
 The *type* of spatial relationship between objects must be considered when undertaking spatial operations, as described in Section \@ref(topological-relations), on topological relations between vector features.
