How common is it to take off from a taxiway? shape_noclip() returns the appropriate columns of its The first one is the clipping function and the second is the plotting function. How can an accidental cat scratch break skin but not damage clothes? mean? This post assumes you already know how to build a basic network In Europe, do trains/buses get transported by ferries with the passengers inside? ', and global parameters have no prefix. el argument. The vertex is referenced by its index, so if the underlying graph changes, the semantics of the vertex object might change as well (if the vertex indices are altered in the original graph). Also, a nerdy request: I wasnt able to find a way to put the country labels outside the graph, next to the nodes. Vertex. Because were plotting the entire graph in a circle, and igraph lays out its nodes predictably when plotting in a circle, we can take advantage of this and calculate the right position for each label with respect to its vertex given the vertexs position on the big circle. Here's an example from this gist.

Named list, additional plot/vertex/edge To attain moksha, must you be born as a Hindu? The element named define the new parameters, and the Vertex labels: positions depend on length. vertex.label.degree: It defines the position of the vertex labels, relative to the center of the vertices. The igraph documentation says that the alignment of a label with respect to its vertex is controlled by vertex.label.degree, and that It is interpreted as an angle in radian, zero means 'to the right', and 'pi' means to the left, up is -pi/2 and down is pi/2. # all vertex shapes, minus "raster", that might not be available, # add new vertex shape, plot nothing with no clipping, #################################################################, # generic star vertex shape, with a parameter for number of rays, # no clipping, edges will be below the vertices anyway. label_color. The plotting function has the following arguments: The coordinates of the vertices, a matrix with two i've tried to change vertex.label.cex and vertex.label.dist parameters but labels still located in the corner of the plot and look messy.
