## Helpers for Data Analysis and Presentation Focused on Undergrad Psychology

Contains functions for the easy display of statistical tests as well as
some convenience functions for data cleanup. It is meant to ease existing workflows
with packages like 'sjPlot', 'dplyr', and 'ggplot2'. The primary components are the functions
prefixed with 'tadaa_', which are built to work in an interactive environment, but also print
tidy markdown tables powered by 'pixiedust' for the creation of 'RMarkdown' reports.

## Readme

# tadaatoolbox

This is **tadaatoolbox** version `0.16.1`

(semver(ish)).

It contains helpers for data
analysis and presentation focused on undergrad psychology, the target
audience being students at University of Bremen.

Please consider this as a teaching project and be careful if you intend
to use it for production use.

To see what’s new, see
NEWS.md.

Also, since this project is still in the `0.x.y`

version, you should
expect the API to change at any time. Once we reach `1.0.0`

, API changes
will be rolled out more slowly and include depracation warnings. In the
meantime, the package is available on CRAN primarily for convenience,
because its target audience is likely not familiar with GitHub or
`devtools`

.

# Installation

Install the current development version from GitHub (recommended):

```
if (!("remotes" %in% installed.packages())){
install.packages("remotes")
}
remotes::install_github("tadaadata/tadaatoolbox")
```

Or install the most recent stable version from CRAN:

```
install.packages("tadaatoolbox")
```

# Functionality

See the included vignette for a demonstration:
`browseVignettes("tadaatoolbox")`

or view the `pkgdown`

ed version of
this repo for an overview and
function index.

Here’s a few highlights:

## Tidy (as in pretty) test output

See all of them in action in this vignette

`tadaa_aov`

: For 3 flavours of`aov`

with included partial (\eta^2), Cohen’s f and power.`tadaa_kruskal`

: A wrapper for`kruskal.test`

tidied and optionally`pixiedust`

ed.`tadaa_t.test`

: For`t.test`

with automatic homogenity of variance detection, effect size and power.`tadaa_wilcoxon`

: A wrapper for`wilcox.test`

tidied and optionally`pixiedust`

ed.`tadaa_levene`

: Wrapper for`car::leveneTest`

tidied and optionally`pixiedust`

ed.`tadaa_normtest`

lets you do tests for normality (4 methods) over multiple variables.`tadaa_pairwise_t`

,`tadaa_pairwise_gh`

and`tadaa_pairwise_tukey`

for various pairwise procedures.

## Helpers for plots

`tadaa_int`

: Simple interaction plot template.`tadaa_balance`

: Check equality of group sizes.`tadaa_mean_ci`

: Plots means with 95% confidence intervals as errorbars.`tadaa_plot_tukey`

: For pretty`TukeyHSD`

visualization.
