as_tibble function

Extract the active element of a sfnetwork as spatial tibble

The sfnetwork method for as_tibble is conceptually different. Whenever a geometry list column is present, it will by default return what we call a 'spatial tibble'. With that we mean an object of class c('sf', 'tbl_df') instead of an object of class 'tbl_df'. This little conceptual trick is essential for how tidyverse functions handle sfnetwork objects, i.e. always using the corresponding sf method if present. When using as_tibble on sfnetwork objects directly as a user, you can disable this behaviour by setting spatial = FALSE.

## S3 method for class 'sfnetwork'
as_tibble(x, active = NULL, spatial = TRUE, ...)

Arguments

• x: An object of class sfnetwork.
• active: Which network element (i.e. nodes or edges) to activate before extracting. If NULL, it will be set to the current active element of the given network. Defaults to NULL.
• spatial: Should the extracted tibble be a 'spatial tibble', i.e. an object of class c('sf', 'tbl_df'), if it contains a geometry list column. Defaults to TRUE.
• ...: Arguments passed on to as_tibble.

Returns

The active element of the network as an object of class tibble.

Examples

library(tibble, quietly = TRUE)

net = as_sfnetwork(roxel)

# Extract the active network element as a spatial tibble.
as_tibble(net)

# Extract any network element as a spatial tibble.
as_tibble(net, "edges")

# Extract the active network element as a regular tibble.
as_tibble(net, spatial = FALSE)
