Issue with SpatVector wrapping when plotting

Question

When plotting a SpatVector using ggplot2, if I define a projection using coord_sf(), it adds these lines that I think come from the data wrapping around the plot extent. Best way to fix?

library(ggplot2)
library(tidyterra)
library(terra)
library(rnaturalearth)

coast <- rnaturalearth::ne_coastline(returnclass = "sv")

ggplot() +
  geom_spatvector(data = coast) +
  theme_minimal()

ggplot() +
  geom_spatvector(data = coast) +
  coord_sf(crs = "+proj=robin",) +  # Robinson projection
  theme_minimal()

Answer 1

Use the terra::normalize.longitude() function to correct this:

library(ggplot2)
library(tidyterra)
library(terra)
library(rnaturalearth)

coast <- ne_coastline(returnclass = "sv")
coast <- normalize.longitude(coast)

ggplot() +
  geom_spatvector(data = coast) +
  coord_sf(crs = "+proj=robin") +
  theme_minimal()
