| network.vertex {network} | R Documentation |
network.vertex adds one or more vertices (drawn using polygon) to a plot.
network.vertex(x, y, radius = 1, sides = 4, border = 1, col = 2,
lty = NULL, rot = 0, ...)
x |
a vector of x coordinates. |
y |
a vector of y coordinates. |
radius |
a vector of vertex radii. |
sides |
a vector containing the number of sides to draw for each vertex. |
border |
a vector of vertex border colors. |
col |
a vector of vertex interior colors. |
lty |
a vector of vertex border line types. |
rot |
a vector of vertex rotation angles (in degrees). |
... |
Additional arguments to polygon |
network.vertex draws regular polygons of specified radius and number of sides, at the given coordinates. This is useful for routines such as plot.network, which use such shapes to depict vertices.
None
network.vertex is a direct adaptation of gplot.vertex from the sna package.
