InteractionPoweR 0.2.4

• Adds citation information and minor bug 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.
