papaja: Prepare APA journal articles with R Markdown

Project Status: WIP - Initial development is in progress, but there has not yet been a stable, usable release suitable for the public. Build status

papaja is an R package in the making including an R Markdown template that can be used with (or without) RStudio to produce documents which conform to the American Psychological Association (APA) manuscript guidelines (6th Edition). The package uses the LaTeX document class apa6 and a .docx-reference file, so you can create PDF documents, or Word documents if you have to. Moreover, papaja supplies R-functions that facilitate reporting results of your analyses in accordance with APA guidelines.

If you are looking for an in-depth introduction to papaja, check out the current draft of the manual.

papaja is in active development and should be considered alpha. If you experience any problems, ask a question on Stack Overflow using the papaja tag or open an issue on Github.

Examples

Take a look at the R Markdown-file of the example manuscript in the folder example and the resulting PDF. The example document also contains some basic instructions. For an in-depth introduction to papaja, check out the current draft of the manual.

Installation

To use papaja you need either an up-to-date version of RStudio or pandoc. If you want to create PDF- in addition to DOCX-documents you additionally need a TeX distribution. If you have no use for TeX beyond rendering R Markdown documents, I recommend you use TinyTex. TinyTex can be installed from within R as follows.

if(!"tinytex" %in% rownames(installed.packages())) install.packages("tinytex")

tinytex::install_tinytex()

Otherwise consider MikTeX for Windows, MacTeX for Mac, or TeX Live for Linux. Please refer to the papaja manual for detailed installation instructions.

papaja is not yet available on CRAN but you can install it from this repository:

# Install devtools package if necessary
if(!"devtools" %in% rownames(installed.packages())) install.packages("devtools")

# Install the stable development verions from GitHub
devtools::install_github("crsh/papaja")

# Install the latest development snapshot from GitHub
devtools::install_github("crsh/papaja@devel")

How to use papaja

Once papaja is installed, you can select the APA template when creating a new Markdown file through the RStudio menus.

APA template selection

If you want to add citations specify your BibTeX-file in the YAML front matter of the document (bibliography: my.bib) and you can start citing. If necessary, have a look at R Markdown’s overview of the citation syntax. You may also be interested in citr, an R Studio addin to swiftly insert Markdown citations.

Helper functions to report analyses

The functions apa_print() and apa_table() facilitate reporting results of your analyses. Take a look at the R Markdown-file of the example manuscript in the folder example and the resulting PDF.

Drop a supported analysis result, such as an htest- or lm-object, into apa_print() and receive a list of possible character strings that you can use to report the results of your analysis.

my_lm <- lm(Sepal.Width ~ Sepal.Length + Petal.Width + Petal.Length, data = iris)
apa_lm <- apa_print(my_lm)

One element of this list is apa_lm$table that, in the case of an lm-object, will contain a complete regression table. Pass apa_lm$table to apa_table() to turn it into a proper table in your PDF or Word document.

apa_table(apa_lm$table, caption = "Iris regression table.")

Table. Iris regression table.

Predictor b 95% CI t(146) p
Intercept 1.04 [0.51, 1.58] 3.85 < .001
Sepal Length 0.61 [0.48, 0.73] 9.77 < .001
Petal Width 0.56 [0.32, 0.80] 4.55 < .001
Petal Length -0.59 [-0.71, -0.46] -9.43 < .001

papaja currently provides methods for the following object classes:

A-B B-L L-S S-Z
afex_aov BFBayesFactorTop* lm summary.glht*
anova default lsmobj* summary.glm
Anova.mlm emmGrid* manova summary.lm
aov glht* summary_emm* summary.ref.grid*
aovlist glm summary.Anova.mlm
BFBayesFactor* htest summary.aov
BFBayesFactorList* list summary.aovlist

* Not fully tested, don’t trust blindly!

Plot functions

Be sure to also check out apa_barplot(), apa_lineplot(), and apa_beeplot() (or the general function apa_factorial_plot()) if you work with factorial designs:

apa_factorial_plot(
  data = npk
  , id = "block"
  , dv = "yield"
  , factors = c("N", "P", "K")
  , ylim = c(0, 80)
  , level = .34
  , las = 1
  , ylab = "Yield"
  , plot = c("swarms", "lines", "error_bars", "points")
)

If you prefer creating your plots with ggplot2 try theme_apa().

Using papaja without RStudio

Don’t use RStudio? No problem. Use the rmarkdown::render function to create articles:

# Create new R Markdown file
rmarkdown::draft(
  "mymanuscript.Rmd"
  , "apa6"
  , package = "papaja"
  , create_dir = FALSE
  , edit = FALSE
)

# Render manuscript
rmarkdown::render("mymanuscript.Rmd")

Using papaja with CodeOcean

Seth Gree has kindly prepared a minimal papaja example capsule. If you want to use papaja in your next CodeOcean project you can use this capsule as a starting point.

Getting help

For an in-depth introduction to papaja, check out the current draft of the manual. If you have questions related to the use of papaja that are not answered in the manual, StackOverflow has a papaja-tag and is a great place to get answers. If you think you have found a bug, please open issues and provide a minimal complete verifiable example.

Contribute

Like papaja and want to contribute? Take a look at the open issues if you need inspiration. Other than that, there are many output objects from analysis methods that we would like apa_print() to support. Any new S3/S4-methods for this function are always appreciated (e.g., factanal, fa, lavaan, lmer, or glmer).

Papers written with papaja

Please cite papaja if you use it (citation('papaja') will provide the reference). Below are some peer-reviewed publications that used papaja. If you have published a paper that was written with papaja, you can add the reference to the public Zotero group yourself or send it to me.
