## EDMAinR 2023-08-21 (2023-08-21)

`edma_scale`

function contributed by Kevin M. Middleton (PR #11).

## EDMAinR 2021-12-07 (2021-12-07)

`read_xyz`

don't change landmark names to be syntactically valid.

## EDMAinR 2021-11-04 (2021-11-04)

- Separate
`edma_fdm_report`

and `edma_gdm_report`

functions.
- Renaming
`Tobs_*`

functions to `global_*`

to avoid confusion with T-test.
- Updated documentation.

## EDMAinR 2021-08-17 (2021-08-17)

- Added
`edma_report()`

to reproduce WinEDMA output.
- Fixed CI calculation:
`ref_denom`

argument should not flip
numerator and denominator.
- 2D and 3D plot revised to color edges and label landmarks.

## EDMAinR 2021-07-19 (2021-07-19)

- Bug fix: FDM methods had issues with B=0.
- Added landmark names to 2D plots, use
`labels=TRUE`

.
- 3D plots now preserve XYZ aspect ration of 1.
`signif_only=FALSE`

allows plotting the top/bottom percentage
of linear distances (edges) in 2D/3D plots.

## EDMAinR 2020-12-19 (2020-12-19)

- Added new function
`gpa_fit`

to estimate mean form based on GPA.

## EDMAinR 2020-11-27 (2020-11-27)

- Renaming
`T_*`

functions to `Tobs_*`

to avoid confusion with T-test.
- Observed statistic not included into the null distribution for global testing.
- Added interactive plotly graphics to vignettes.

## EDMAinR 2020-11-20 (2020-11-20)

- Shape difference matrix (SDM) calculation added:
`edma_sdm`

.
`edma_sdm`

can be set to assume same size, use TLS, or a particular edge.
- CI calculation (local FDM, GM, GDM, SDM testing) calculations use
2-sample bootstrap.
- Global FDM, GM, GDM testing (T-test) uses the mixed or the reference
bootstrap, global Z-test for FDM is based on 2-sample bootstrap.

## EDMAinR 2020-08-23 (2020-08-23)

`.edma_fit_np`

is more preformant (original implementation
retained as `.edma_fit_np_old`

for comparison);
it also exposes mean/variance for distances for future uses.
`edma_simulate_data`

is also much faster now.
- Nonparametric EDMA fid and FDM analysis can use multiple cores.
- Added
`write.xyz`

function to write EDMA data into xyz format.
- Added 4 data sets for growth difference analysis.

## EDMAinR 2020-07-05 (2020-07-05)

- Small fixes to parametric test helper functions.
- Miscellaneous function to print/visualize pattern matrices.
- Exposed
`combine_data`

and `combine_data4`

functions.
- Clustering method now can be changed by the user.
`as.edma_data`

method added to turn a 3D array (a common
morphometrics data format) to EDMA data objects.
- Added
`edma_colors`

and `plot_edma_colors`

for
manipulating color palettes set via `getOption("edma_options")`

.
- Extensive updates to the docs and vignettes.

## EDMAinR 2020-04-30 (2020-04-30)

- Parametric estimation tested.

## EDMAinR 2020-02-16 (2020-02-16)

- Global test p-values updated.
- Package website made with {pkgdown}.

## EDMAinR 2019-12-27 (2019-12-27)

- EDMA package command line interface finalized.
