Package: eddington Title: Compute a Cyclist's Eddington Number Version: 4.3.0 Authors@R: c( person('Paul', 'Egeler', email = 'paulegeler@gmail.com', role = c('aut','cre')), person('Tashi', 'Reigle', role = 'ctb')) Description: Compute a cyclist's Eddington number, including efficiently computing cumulative E over a vector. A cyclist's Eddington number is the maximum number satisfying the condition such that a cyclist has ridden E miles or greater on E distinct days. The algorithm in this package is an improvement over the conventional approach because both summary statistics and cumulative statistics can be computed in linear time, since it does not require initial sorting of the data. These functions may also be used for computing h-indices for authors, a metric described by Hirsch (2005) . Both are specific applications of computing the side length of a Durfee square . Some additional author-level metrics such as g-index and i10-index are also included in the package.
