This function calculates the Rao-Stirling diversity index of a single publication, based on its proportions of citations to different disciplines.


RaoProportions(proportions, similarity)



A vector of proportions of citations to different disciplines of a single publication. Since the elements of this vector are proportions, they need to be within the interval [0,1].


A positive semi-definite matrix that encodes the similarity between disciplines, as explained in Porter and Rafols (2009). The dimensions of this matrix are n x n, being n the total number of disciplines. The number of rows and the number columns of this matrix need to be equal to the length of counts. The self-similarities (i.e. the diagonal elements) have to be 1.


The Rao-Stirling diversity index of a publication.
