"neato" allows you to set several edge attributes, a close one to what you want is "style", which could be solid/bold/dotted/dashed. It seems that currently only "solid" works well.

Hi S?ren, S?ren H?jsgaard <soren.hojsgaard at="" agrsci.dk=""> writes: > I create an undirected graph with Rgraphviz (see code below). I > would like to make the edges thicker. Can anyone help on this?? I don't think there is any easy way to achieve this in the current released verison of Rgraphviz. However, in the devel version, code has been added to allow specifying lwd (width) and lty (type) for the edges. To use this feature, one needs to add lwd and/or lty members to the edge attributes list (your eAttrs below). + seth
