What the Package Does (One Line, Title Case)

demopkg

The goal of demopkg is to provide data and analysis code for the paper “Facial resemblance increases the attractiveness of same-sex faces more than other-sex faces” (DeBruine, 2004).

Installation

You can install the development version of demopkg from GitHub with:

# install.packages("devtools")
devtools::install_github("debruine/demopkg")

Example

library(demopkg)

# load attractiveness judgement data 
data("self_res_att")

# analyse female faces
apa_t_pair(x = self_res_att$f_self,
           y = self_res_att$f_non,
           dv = "preferences for female faces",
           level1 = "participants who resembled those faces",
           level2 = "non-self participants")
#> A paired-samples t-test was conducted to compare preferences for female faces between participants who resembled those faces (M = 3.5, SD = 1.6) and non-self participants (M = 3, SD = 1.2). There was a significant difference; t(197.2) = 2.92, p = 0.004.

# analyse male faces
apa_t_pair(x = self_res_att$m_self,
           y = self_res_att$m_non,
           dv = "preferences for male faces",
           level1 = "participants who resembled those faces",
           level2 = "non-self participants")
#> A paired-samples t-test was conducted to compare preferences for male faces between participants who resembled those faces (M = 3.5, SD = 1.4) and non-self participants (M = 2.9, SD = 1). There was a significant difference; t(190.9) = 3.83, p = 0.
