, defaulting to var.equal = FALSE
as stats::t.test()
does. Turns out this was a pretty bad idea due to the multiplicity problem, and the Welch-test is good enough.power

tadaa_pairwise_t
as an extension of stats::pairwise.t.test
that works with two grouping factors and thereby can test interactions.
tadaa_pairwise_gh
for the Games Howell post-hoc procedure as an alternative to TukeyHSD
.tadaa_pairwise_tukey
while we're at it. Just a thin wrapper for stats::TukeyHSD
but with tidied output and usage consistent with the previous tadaa_pairwise_*
functions.tadaa_plot_tukey
to plot Tukey HSD results as error bars because boy do I like error bars.tadaa_balance

: Was a wrapper around haven::as_factor
