“Jade”

• Minor fix to the plot_power function
• Major updates to the Shiny apps
  • Changes design input to a more friendly UI

"Green Lantern"

This is a major update to the Superpower R package.

• ANCOVAs are now supported with the ANCOVA_analytic, ANCOVA_contrast, and power_oneway_ancova functions.
• Names of factors and factor levels can now be assigned with label_list (a named list with the names of each factor level as a vector for each name in the list)

"Black Canary"

In this release we have added the "morey_plots" functions which allow for the calculation of the sensitivity of t-test and f-test to detect a range of effect sizes.

Further, minor errors have been resolved with some of the existing functions.

JustifieR edition

In this release, we have added 4 new functions to help "justify your alpha" (optimal_alpha, ANOVA_compromise, p_standardized, alpha_standardized). Further, ANOVA_exact2 has been created which mimics ANOVA_exact, but instead of creating an exact dataset it calculates the standardized effect sizes from a larger sample size then back calculates power for the provided N. This removes the sample size limitations/issues associated with the original ANOVA_exact function. In addition, S3 methods have been created for ANOVA_design, and simulation results (ANOVA_exact and ANOVA_power).

v0.0.4 emmeans_power

Added new function by @crsh
-emmeans_power function; extends Superpower's capability to perform power analyses for estimated marginal means

First full release

This is a stable release, and will be submitted to CRAN. See NEWS file for new updates.
