- Add
`tadaa_chisq`

for a*χ*^{2}-Test with OR and effect size.

- Switched from
`sjmisc`

to the new`sjlabelled`

(Thanks, @strengejacke!) - Also re-export
`magrittr::%$%`

because it’s really handy*sometimes*.

- Add
`tadaa_pairwise_t`

as an extension of`stats::pairwise.t.test`

that works with two grouping factors and thereby can test interactions. - Add
`tadaa_pairwise_gh`

for the Games Howell post-hoc procedure as an alternative to`TukeyHSD`

.- Adapted from this gist by GitHub user aschleg
- Further reading

- Add
`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. - Add
`tadaa_plot_tukey`

to plot Tukey HSD results as error bars because boy do I like error bars. - Add
`tadaa_balance`

as a replacement for`tadaa_heatmap`

to check equality of group sizes. - Re-exports:
`%>%`

from`magrittr`

as all the cool kids to these days.`%<>%`

from`magrittr`

because I happen to really like it.`[sg]et_label[s]`

and`word_wrap`

from`sjmisc`

, as they’re handy.`as_factor`

from`haven`

as a replacement for the deprecated`labels_to_factor`

.

`theme_tadaa`

:- Is now an alias for
`theme_readthedown`

, will probably become the new canonical version. - Now finally adds vertical space to the
`x`

axis title via proper margining.

- Is now an alias for
`tadaa_aov`

:- Default
`type`

is now`3`

, for generally safer results and consistency with SPSS. - Added
`check_contrasts`

option for`type = 3`

sums of squares, which ensures each non-ordered factor has`contr.sum`

contrasts - Now auto-factorizes independent variables by default, fixes #24.
- Now imports
`methods`

, which should fix an issue during`knitr`

or`rmarkdown`

processing where the function`is`

couldn’t be found. If not, manually`library(methods)`

as a workaround. - Fix wrong
`sprinkle`

labelling causing`eta.sq`

to be formatted like a p-value. - Added
`show_power`

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

.- Requires more testing against software like G*power to ensure accuracy.

- Default
`tadaa_t.test`

:- Internal Levene test now uses
`center = "median"`

for more robust results, as it should.- Now also uses
*α*= 0.05 instead of*α*= 0.1. - Use new argument
`var.equal`

to override internal Levene test.

- Now also uses
- Power should now be properly reported for
`alternative = "less"`

or`greater`

. - Added
`conf.level`

argument used for CI and power calculations `effect_size_t`

:- Now doesn’t return the absolute effect size by default.
- Added
`paired`

argument so effects for paired tests are now a thing.

- Internal Levene test now uses
`tadaa_wilcoxon`

:- Also fix
`direction`

argument not being honored.

- Also fix
`tadaa_int`

:- Gains
`print`

(logical) argument to suppress printing if so desired. The output will still be returned invisibly.

- Gains
`tadaa_one_sample`

: Should make sense now.- Remove
`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. - Documentation improvements
- Improved
`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.- Method for effect size calculation now uses
`lsr::etaSquared`

, which also takes a`type`

argument.

- Method for effect size calculation now uses
- Add
`tadaa_mean_ci`

: Plots means with 95% confidence intervals as errorbars (thanks Christoph for the suggestion). - Add
`tadaa_one_sample`

: For one-sample t-tests and finally an easy z-test.- Add
`confint_norm`

: Helper to get CIs, similar to`confint_t`

- Add
- Add
`tadaa_wilcoxon`

: For when`tadaa_t.test`

isn’t non-parametric enough. Same usage.- Additionally displays medians of each group.

- Add
`tadaa_kruskal`

: For when`tadaa_aov`

isn’t non-parametric enough, too. - Move
`tadaa_sem`

➡`mean_ci_sem`

because it’s more`confint`

than`tadaa`

. - Add
`show_n`

option to`tadaa_int`

: Optionally display N in subtitle.

- Fix documentation inconsistencies.
- Turns out
`pval_string(0.05)`

returned`< 0.05`

. Well. That was embarrassing. - Minor tweaks to
`theme_readthedown`

regarding text placement.

- Remove superfluous variables from
`ngo`

:`index`

,`zeng`

,`zdeutsch`

,`zmathe`

.

- New function:
`tadaa_normtest`

lets you do tests for normality (4 methods) over multiple variables. - New function:
`tadaa_heatmap`

generates a heatmap. Mhhh, heatmaps. - New function:
`tadaa_sem`

shows the standard error of the mean and it’s confidence interval - New function:
`pval_string`

as a modification of`pixiedust::pvalString`

that includes`p < .05`

. - Added a ggplot2 theme for the rmdformats::readthedown Rmd template.
`tadaa_aov`

,`tadaa_t.test`

and the new`tadaa_normtest`

now return a`data.frame`

by default, allowing further shenanigans

- New options in
`tadaa_int`

:- Set
`grid = TRUE`

for the two interaction plots to be printen in a grid via cowplot::plot_grid.

- Choose the plot labels via the
`labels`

argument.

- Set
`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`

, G*power)- Add option
`reduce`

to`modus`

, so multiple results will be concatenated to a character by default. - Add additional option
`as_character`

to`modus`

because guessing about return value classes is no joke. - Fix issues with
`generate_recodes`

and`interval_labels`

(#1).

- Add
`tadaa_ord`

as ordinal equivalent of`tadaa_nom`

. - Make table output of both of the former functions smaller in width by abbreviating column names
- Add
`brewer_palette`

option to`tadaa_int`

- Dependencies declared in
`DESCRIPTION`

are still experimental because of uncertainty regarding failing travis builds. I don’t know what’s going on there.

- Add
`family`

tag to`tadaa_`

functions so their documentation is linked - Fix return values of
`tadaa_aov`

,`_t.test`

and`_nom`

which did not work as I expected

- Fix typo in
`DESCRIPTION`

, misspelling`pixiedust`

. Sorry! - Bump dependencies
`pixiedust`

depends on R (>= 3.2.1), so we might as well depend on that version, too- Specifiy minimal versions for
`pixiedust`

,`sjmisc`

, and`broom`

, just to be safe

- Add vignette
- Overhauling
`README`

to be less redundant compared to the usage vignette

- Overhauling

- Added a
`NEWS.md`

file to track changes to the package. - Working on CRAN compatibility
- Submitted to CRAN
- It’s on CRAN, yay!
