# R Packages

## [ggdiagram](https://wjschne.github.io/ggdiagram/)

::::{.columns}
:::{.column width=70%}
[An object-oriented approach to making diagrams via ggplot2]{.lead}

Complex diagrams can take a long time to get right. The ggdiagram package can take away much of the burden of tedious calculation.

## [simstandard](https://wjschne.github.io/simstandard/index.html) 

::::{.columns}
:::{.column width=70%}
[R package for simulating data using standardized coefficients]{.lead}

In the model below, the path coefficients are standardized. You would like to simulate the variables in the model, but you do not know the disturbance and residual variances. The simstandard package can help.

## [ggnormalviolin](https://wjschne.github.io/ggnormalviolin/index.html)

I needed to show confidence intervals and conditional normal distributions with specific means and standard deviations. I wrote the ggnormalviolin package to make this happen.

It makes plots like this:

## [psycheval](https://wjschne.github.io/psycheval/)

:::{.column width=70%}
[Functions useful for psychological evaluations]{.lead}

This package is still in a preliminary state, just like [Individual Psychometrics](https://individual-psychometrics.rbind.io/), the book it accompanies.

Making digital spirographs is fun! I made an R package called [spiro](https://wjschne.github.io/spiro/index.html) that can make animated spirographs like this one:

## [arrowheadr](https://wjschne.github.io/arrowheadr/)

::::{.columns}
:::{.column width=70%}

The arrowheadr package allows one to create custom arrowheads that can be used with the [ggarrow](https://github.com/teunbrand/ggarrow) package.

# Quarto Extensions

## [apaquarto](https://github.com/wjschne/apaquarto)

[A Quarto Extension for Creating APA 7 Style Documents]{.lead}

This is a quarto article template that creates [APA Style 7th Edition documents](https://apastyle.apa.org/) in .docx, .html. and .pdf. I made this extension for my own workflow. If it helps you, too, I am happy. The output of the template is displayed below:
