netplot 0.4-0

  • Attribute formulas for vertex.nsides, vertex.size, and edge.width now evaluate the right-hand side against the graph’s attributes, so expressions such as edge.width = ~ log1p(weight) or vertex.size = ~ degree ^ 2 work in addition to bare attribute names. Previously any non-trivial right-hand side failed with a cryptic the condition has length > 1 error. Missing attributes now produce a clear, informative message.

  • vertex.color = ~ attr now draws a legend appropriate to the attribute type: a categorical key for discrete attributes (factor, logical, low-cardinality integer) and a continuous color bar for continuous ones.

  • Documentation overhaul: nplot() now documents the formula interface for mapping vertex/edge aesthetics from graph attributes, the README highlights what sets netplot apart, a package-level help page was added, and the pkgdown reference is organized by feature.

  • New vignette "formulas" demonstrating how to color, shape, and size vertices (and scale edge widths) from graph attributes using formulas.

  • nplot.network() now uses the "weight" edge attribute for edge.width by default (like nplot.igraph() already did), so edge widths reflect edge weights instead of being drawn uniformly. edge.width values are also explicitly re-applied to each edge grob after color post-processing to keep the drawn line widths robust. Closes #17.

  • edge.width.range, vertex.size.range, and vertex.label.range now accept NULL to suppress scaling and use the supplied values as-is.

  • Fixed vertex.rot, which was truncated to an integer and so ignored fractional (radian) rotations; the named "square" shape orientation was corrected as well.

  • edge.line.lty is now validated to be length 1 or one value per plotted edge, and is subset correctly when sample.edges drops edges.

netplot 0.3-0

CRAN release: 2024-06-30

  • Invalid arguments passed to nplot() now raise an error.

  • Figures with legends are not drawn twice.

  • Values supported by nplot() are now included in all methods (helps with argument completion).

  • Changed some default values for better results.

  • The arguments skip.vertex, skip.edges, and skip.arrows now work as documented.

  • New function nplot_legend() helps to add legends to the figure.

  • New nplot() method for matrices.

  • New feature: Gradients.

  • The argument sample.edges now work as expected.

  • vertex.color, vertex.size, and vertex.nsides now accepts formulas.
