geo_filter: Subset a geometric object using column values

In EhrmannS/geometr: Generate and Modify Interoperable Geometric Objects

Subset a geometric object using column values

Description

This function allows to subset any geometric object for which all required getters are available.

Usage

geo_filter(obj, ..., update = TRUE)

Arguments

obj	gridded(1) the object to derive a subset from.
...	subset based on logical predicates defined in terms of the columns in x (of both, points, features and groups). Multiple conditions are combined with &. Only rows where the condition evaluates to TRUE are kept.
update	logical(1) whether or not to update the window slot after deriving the subset.

Value

geom of the subset of obj.
