Changes:

• Added bibliometric index calculations h_index(), g_index(), and i10_index() as well as an index() function factory for making custom index calculations.
• Aliased E_num() to durfee() to aid in search.
• Created a daily_totals dataset that aggregates the rides dataset by day.

Changes:

• Substituted XML package dependency for xml2.

Changes:

• Enhanced and fixed typos in examples.
• Changed API to get_haversine_distance().

Changes:

• Supports ingesting GPS Exchange Format (GPX) files. Creates a data.frame where each row contains the distance of a track segment and date.

Changes:

• Minimum R version is now 4.3.0 and requires compiler capable of C++17 standard.
• Full re-implementation of C++ code. As a result, memory usage will be reduced for typical datasets.
• Introduction of EddingtonModule() Rcpp module. This class maintains algorithm state, and so can be updated multiple times as new data comes in.
• Introduction of Eddington() R6 class. This provides similar functionality to the EddingtonModule() Rcpp module. All methods are implemented in pure R. It uses R's new hashtab() data structure, which is experimental as of this package release.

Changes:

• Functionality of E_req() has been migrated to E_next()

eddington 2018-12-17

Changes:

• R version of Eddington_number and c++ E_fast are now defunct.
• E_num() is now the method for getting the single maximum Eddington number of a dataset.
• Added E_sat() that checks to see if a dataset satisfies a certain Eddington number.
• Added E_req() that determines the minimum number of rides to increment Eddington number.
