RGraphSpace: A Lightweight Interface Between 'igraph' and 'ggplot2' Graphics

An interface for rendering 'igraph' objects as 'ggplot2' graphics within a normalized coordinate system. 'RGraphSpace' implements new geometries that treat a graph as a single coherent object, synchronizing node and edge layers under standard aesthetic mappings. Node features are resolved on demand, supporting high-dimensional data without expanding node tables. Spatial registration is available at the pixel level, with node coordinates anchored to pixel centers through a half-pixel offset, enabling precise alignment against external reference frames such as images and maps.

Details

For a hands-on introduction, see the vignette: vignette("RGraphSpace").

The full set of documented topics can also be browsed in HTML by running help.start() and selecting the RGraphSpace package from the package list.
