## ## version 2.0.2

### change for CRAN

- remove sort on a
`data.frame`

from the function
`plot_abu`

which does not change how this function behaves
but adheres to CRAN standards.

## ## version 2.0.1

### new features

`ref_level`

can be specified in
`get_mob_stats`

, `plot_rarefaction`

and
`plot_sad`

which allows for the reference (i.e., control)
group to be specified which all others are compared to. This is similar
to the implementation in the function `get_delta_stats`

### minor bug fixes

- typo in test_rarefaction.R
- typo in get_mob_stats documentation

## 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)
