The sum of these six RIASEC vectors lead to an interest vector that points in one of the RIASEC dimensions and considers full profile information as well as the assumed hexagonal structure of the RIASEC dimensions. The coordinates of such a vector can also be determined by calculating the ...

Vertex names can also be used to specify a vector or set of vertices, in all igraph functions. E.g. degree has a v argument that gives the vertices for which the degree is calculated. This argument can be given as a character vector of vertex names. Edges can also have a ‘name’ ...
After creating the vector, a chi-square test is performed using the chisq.test function: XML Copy > chisq.test(observed) In R, the dot (.) character is often used rather than the underscore (_) character to create variable and function names that are easier to read. The result of ...
