apa7

The goal of apa7 is to facilitate writing documents in APA Style (7th Edition).

Installation

You can install the development version of apa7 with:

install.packages("apa7", repos = c('https://wjschne.r-universe.dev'))

Tables

The package provides functions to create APA-style tables, including correlation matrices and regression tables. The tables can be formatted using the flextable package.

library(apa7)
# Correlation matrix 
apa_cor(trees, star_significant = TRUE)

# Make regression model, format parameters, and display flextable
lm(Volume ~ Girth + Height, data = trees) |> 
  apa_parameters() |> 
  apa_flextable()

# Contingency table with chi-square test of independence
d <- mtcars[, c("am", "gear")]
colnames(d) <- c("Transmission", "Gears")
d$Transmission <- factor(d$Transmission, 
                         levels = c(0, 1), 
                         labels = c("Automatic", "Manual"))
apa_chisq(d)

Formatting functions

The package provides functions to format p-values, numbers, and other statistical results according to APA Style.

# Format p-values
apa_p(c(0.0007, 0.001, 0.0081, 0.024, 0.454))
#> [1] "<.001" ".001"  ".008"  ".02"   ".45"
