gt_filter

Subset a geometric object using column values

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

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

`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.

geom of the subset of obj.

# get a subset of a geom
gt_filter(gtGeoms$point, y < -10)

# get a subset of an sf-object
gt_filter(obj = gtSF$multilinestring, a == 1)
