Description Usage Arguments Value References Examples

This function calculates the Rao-Stirling diversity index of one or several publications, based on the count of citations of the publication(s) to different disciplines.

1 | ```
RaoStirling(count.matrix, similarity)
``` |

`count.matrix` |
Vector or matrix that contains the counts of references to different disciplines of a single publication (vector) or of several publications (matrix).
If count.matrix is a vector its length is equal to the total number of disciplines.
In case it is a matrix its dimensions are |

`similarity` |
A positive semi-definite matrix that encodes the similarity between disciplines, as explain in Porter and Rafols (2009).
The dimensions of this matrix are |

The Rao-Stirling diversity index of one or several publications.
