Duplicate SpatVector rows

uncount() duplicates rows according to a weighting variable.

Usage

# S3 method for class 'SpatVector'
uncount(data, weights, ..., .remove = TRUE, .id = NULL)

Arguments

data

A SpatVector.

weights

A vector of weights. Evaluated in the context of data; supports quasiquotation.

...

Additional arguments passed on to methods.

.remove

If TRUE, and weights is the name of a column in data, then this column is removed.

.id

Supply a string to create a new variable which gives a unique identifier for each created row.

Value

A SpatVector object.

Methods

Implementation of the generic tidyr::uncount() method.

Each duplicated row keeps the geometry of the input feature.
