gt_filter: Subset a geometric object using column values

In geometr: Generate and Modify Interoperable Geometric Shapes

Description

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

Usage

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

Arguments

obj	[geometric object(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.
