Create a SpatVectorCollection

Description

Methods to create a SpatVectorCollection. This is an object to hold "sub-datasets", each a SpatVector, perhaps of different geometry type.

Usage

## S4 method for signature 'missing'
svc(x, ...) 

## S4 method for signature 'SpatVector'
svc(x, ...) 

## S4 method for signature 'list'
svc(x, ...)

Arguments

`x`	SpatVector, or list of SpatVector objects, or missing
`...`	additional arguments. Can be other `SpatVector` objects if `x` is a `SpatVector`

Value

SpatVectorCollection

Examples

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
x <- svc()
x <- svc(v, v[1:3,], as.lines(v[3:5,]), as.points(v))
length(x)
x

# extract
x[3]
