Description

arrange.SpatVector() orders the geometries of a SpatVector by the values of selected columns.

Usage

# S3 method for SpatVector
arrange(.data, ..., .by_group = FALSE)

Value

A SpatVector object.

Arguments

.data

A SpatVector created with terra::vect().

...

<data-masking> Variables, or functions of variables. Use desc() to sort a variable in descending order.

.by_group

If TRUE, will sort first by grouping variable. Applies to grouped SpatVector only (see group_by.SpatVector()).

library(dplyr)

v <- vect(system.file("extdata/cyl.gpkg", package = "tidyterra"))


# Single variable

v %>%
  arrange(desc(iso2))


# Two variables
v %>%
  mutate(even = as.double(cpro) %% 2 == 0, ) %>%
  arrange(desc(even), desc(iso2))


# With new variables
v %>%
  mutate(area_geom = terra::expanse(v)) %>%
