Hi Moses,
from the manual:
• curved
Specifies whether to draw curved edges, or not. This
can be a logical or a numeric vector or scalar.
First the vector is replicated to have the same length as the
number of edges in the graph. Then it is interpreted for each
edge separately. A numeric value specifies the curvature of
the edge; zero curvature means straight edges, negative
values means the edge bends clockwise, positive values the
opposite. ‘TRUE’ means curvature 0.5, ‘FALSE’ means curvature
zero.
This parameter is ignored for loop edges.
The default value is ‘FALSE’.
This parameter is currently ignored by ‘rglplot’.
Best,
Gabor
