Arguments

x	A graph. It supports networks stored as igraph, network, and matrices objects (see details).
layout	Numeric two-column matrix with the graph layout in x/y positions of the vertices.
vertex.size	Numeric vector of length vcount(x). Absolute size of the vertex from 0 to 1.
bg.col	Color of the background.
vertex.nsides	Numeric vector of length vcount(x). Number of sizes of the vertex. E.g. three is a triangle, and 100 approximates a circle.
vertex.color	Vector of length vcount(x). Vertex HEX or built in colors.
vertex.size.range	Numeric vector of length 3. Relative size for the minimum and maximum of the plot, and curvature of the scale. The third number is used as size^rel[3].
vertex.frame.color	Vector of length vcount(x). Border of vertex in HEX or built in colors.
vertex.rot	Vector of length vcount(x) in Radians. Passed to npolygon, elevation degree from which the polygon is drawn.
vertex.frame.prop	Vector of length vcount(x). What proportion of the vertex does the frame occupy (values between 0 and 1).
edge.width	Vector of length ecount(x) from 0 to 1. All edges will be the same size.
edge.width.range	Vector of length ecount(x) from 0 to 1. Adjusting width according to weight.
edge.arrow.size	Vector of length ecount(x) from 0 to 1.
edge.color	A vector of length ecount(x). In HEX or built in colors. Can be NULL in which case the color is picked as a mixture between ego and alters' vertex.color values.
edge.color.mix	Proportion of the mixing.
edge.color.alpha	Either a vector of length 1 or 2, or a matrix of size ecount(x)*2 with values in [0,1]. Alpha (transparency) levels (see details)
edge.curvature	Numeric vector of length ecount(x). Curvature of edges in terms of radians.
edge.line.lty	Vector of length ecount(x). Line types in R (e.g.- 1 = Solid, 2 = Dashed, etc).
edge.line.breaks	Vector of length ecount(x). Number of vertices to draw (approximate) the arc (edge).
sample.edges	Numeric scalar between 0 and 1. Proportion of edges to sample.
skip.vertex, skip.edges, skip.arrows	Logical scalar. When TRUE the object is not plotted.
add	Logical scalar.
zero.margins	Logical scalar.

Value

nplot_base returns a list with the following components:

• vertex.coords A list of length N where each element describes the geomtry of each vertex.

• vertex.color A vector of colors

• vertex.frame.coords Similar to vertex.coords, but for the frame.

• vertex.frame.color Similar to vertex.color, but for the frame.

• edge.color Vector of functions used to compute the edge colors.

• edge.coords Similar to vertex.coords, the points that describe each edge.

• edge.arrow.coords A list of matrices describing the geometry of the tip of the edges.

• edge.width A numeric vector with edges' widths.

• xlim, ylim Limits of the plot area.
