E_cum

This function is much like <code>E_num</code> except it provides
a cumulative Eddington number over the vector rather than a single summary
number.

Compute a cyclist's Eddington number, including efficiently
computing cumulative E over a vector. A cyclist's Eddington number
<https://en.wikipedia.org/wiki/Arthur_Eddington#Eddington_number_for_cycling>
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)
<doi:10.1073/pnas.0507655102>. Both are specific applications of computing
the side length of a Durfee square <https://en.wikipedia.org/wiki/Durfee_square>.
