version 2.0.0

new features

• Gradient multi-scale mob method added to the function get_delta_stats as described in McGlinn et al. (2020
• Added a new k-nearest neighbor algorithm for the spatial sample based rarefaction curve (sSBR)
• ggplot integrated into plotting method for get_delta_stats -> plot.mob_out
• Added automated tests
• Improved documentation throughout the package

bug fixes

• Function sphere_dist did not appear to be calculating great circle distances from latitude and longitude coordinates correctly using the Haversine formula. This was corrected with a new function this is correct according to comparisons with fields::rdist.earth and geosphere::distHaversine.

omitted feature

• Removed the function overlap_effects which provided an overlapped image of the three components SAD, N, and agg across scale. This may be added back in the future

code refactoring

• Refactored code surrounding the get_delta_stats function which computes the differences in richness across all possible scales.
• Refactoring was primarily accomplished by integrating in the tidyverse tools which should make the code easier to understand and follow
• Computational time has increased as the tidyverse tools are not necessarily the most computationally efficient solutions

version 1.0.0

• provided core functionality of mob tools described in McGlinn et al.  (2019) and Chase et al.  (2018)
