# InteractionPoweR 0.2.4

* Minor fixes

# InteractionPoweR 0.2.3

* Adds two-way interaction stability function - `run_pos_power_search()`.

# InteractionPoweR 0.2.2

* Adds power analysis function for 3-way interactions - `power_interaction_3way_r2()`.
* Adds convenience function for visualizing the correlation matrix from a 3-way interaction - `cor.mat.3way()`.
* Adds convenience function for visualizing the simple slopes from a 3-way interaction - `simple.slopes.3way()`.
* Adds power analysis function for 2-way interactions with covariates - `generate.interaction.cov.input()` and `power_interaction_r2_covs()`.
* Minor bug fixes.
* Removes dependency on the {MASS} package.

# InteractionPoweR 0.2.1

* Fix bug in  `power_interaction_r2()` which effected analyses with a high 'r.x1.x2' correlation.
* Fix warning in `plot_interaction()`.
* Adds additional descriptive error messages.

# InteractionPoweR 0.2.0

* Removes options for specifying skew, which contained a bug.
* Also a speed-up for the simulations.

# InteractionPoweR 0.1.1

* First CRAN release.

# InteractionPoweR 0.1.0.6

* Added `power_interaction_r2()` function for analytic power.

# InteractionPoweR 0.1.0.5

* Adds options to simulate ordinal variables (e.g., a likert scale) in `power_interaction()` using the 'k.x1', 'k.x2', and 'k.y' options.
* Also a speed-up and minor bug-fixes.
