Fixes the aspect ratio so brains aren't stretched by the shape of the plotting window. [geom_brain()] adds `coord_brain()` for you, so you rarely need to call it yourself – reach for it only to adjust the `ratio` or `clip` behaviour. You can safely add your own coord or stack several `geom_brain()` layers; it steps aside cleanly.
Arguments
- ratio
Aspect ratio, expressed as `y / x`. Defaults to `1`, which keeps brain polygons undistorted.
- clip
Should drawing be clipped to the panel extent (`"on"`) or allowed to overflow (`"off"`)? Defaults to `"off"` so region outlines at the panel edge are not cut.
- ...
Additional arguments passed to [ggplot2::coord_fixed()].
Examples
library(ggplot2)
if (FALSE) { # \dontrun{
poly <- ggseg.formats::as_polygon_atlas(dk())
# Equivalent to the default; shown explicitly:
ggplot() +
geom_brain(atlas = poly) +
coord_brain()
} # }
