Simplify atlas 2D contours

Reduce vertex count in the sf geometry of a ggseg_atlas object using Douglas-Peucker simplification. Higher tolerance values produce simpler shapes with fewer vertices. This avoids re-running the full atlas creation pipeline.

Usage

atlas_simplify(atlas, tolerance = 0.5)

Arguments

atlas

A ggseg_atlas object with sf data.

tolerance

Simplification tolerance passed to sf::st_simplify(dTolerance). Typical range 0.1–2. Default 0.5.

Value

A modified ggseg_atlas with simplified sf geometry.

Examples

if (FALSE) { # \dontrun{
atlas <- atlas_simplify(my_atlas, tolerance = 1)
plot(atlas)
} # }
