.z.test()
to fill the niche in stats
. Useful to verify hand-made calculations done in educational contexts, as I assume nobody else will ever need a z-test function.tadaa_z.test()
while we’re at it.tadaa_t.test()
, 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

to retrieve N_{c}, N_{d}, ties and total number of pairs for contingency tables. Internals for this function are straight up copied from this gist.etasq
in case you want to show students what η^{2} is without having to explain ANOVA.ord_somers_d

: Use DescTools::SomersDelta

.chisq.test
ord_tau
to calculate all the Taus
tadaa_ord
sjmisc
to the new sjlabelled
(Thanks, @strengejacke!)magrittr::%$%
because it’s really handy sometimes.tadaa_one_sample
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
as a replacement for tadaa_heatmap
to check equality of group sizes.theme_tadaa
:
theme_readthedown
, will probably become the new canonical version.x
axis title via proper margining.tadaa_aov
:
type

argument to calculate power via pwr::pwr.f2.test

:

for more robust results, as it should.
var.equal
to override internal Levene test.alternative = "less"

:
paired
argument so effects for paired tests are now a thing.tadaa_wilcoxon
:

argument not being honored.tadaa_int
:
print
(logical) argument to suppress printing if so desired. The output will still be returned invisibly.tadaa_one_sample
: Should make sense now.na.rm
argument from tadaa_t.test
and tadaa_wilcoxon
because it’s problematic, and in case of paired = TRUE
it would have produced flat out wrong results.print = markdown
output of tadaa_aov
, tadaa_t.test
, tadaa_wilcoxon
, tadaa_one_sample
, tadaa_kruskal
. Unfortunately print = "console"
now has headers with unparsed $\LaTeX$-expressions, but who uses that anyway.labels_to_factor
: Was a wrapper around haven::as_factor
and is obsolete by now, as as_factor
can do the same thing this function was built for.tadaa_likertize
is renamed to likertize
, deprecated since sjmisc::split_var
is probably better anyway.tadaa_aov
now knows about types, uses type 1 by default and can do types 2 and 3.
lsr::etaSquared
, which also takes a type
argument.tadaa_mean_ci
: Plots means with 95% confidence intervals as errorbars (thanks Christoph for the suggestion).tadaa_one_sample
: For one-sample t-tests and finally an easy z-test.
confint_norm
: Helper to get CIs, similar to confint_t
tadaa_wilcoxon
: For when tadaa_t.test
isn’t non-parametric enough. Same usage.
tadaa_kruskal
: For when tadaa_aov
isn’t non-parametric enough, too.tadaa_sem
➡ mean_ci_sem
because it’s more confint
than tadaa

option to tadaa_int
: Optionally display N in subtitle.pval_string(0.05)

. Well. That was embarrassing.theme_readthedown
regarding text placement.tadaa_normtest
lets you do tests for normality (4 methods) over multiple variables.tadaa_heatmap
generates a heatmap. Mhhh, heatmaps.tadaa_sem
shows the standard error of the mean and it’s confidence intervalpval_string
as a modification of pixiedust::pvalString
that includes p < .05
.tadaa_aov
, tadaa_t.test
and the new tadaa_normtest
now return a data.frame
by default, allowing further shenaniganstadaa_int
:
grid = TRUE
for the two interaction plots to be printed in a grid via cowplot::plot_grid.labels
argument.tadaa_int
plot output now also is a little tidier and optimized for smaller widths.tadaa_aov
now also shows Cohen’s f for easier power calculations based on f (pwr

, so multiple results will be concatenated to a character by default.as_character

, misspelling pixiedust
. Sorry!pixiedust
depends on R (>= 3.2.1), so we might as well depend on that version, toopixiedust
, sjmisc
, and broom
, just to be safeREADME
