In LukasWallrich/rNuggets: Useful Helper Functions for (Academic) Data Analysis

Pairwise t-tests() returned in tidy dataframe

Description

This runs pairwise independent-samples t-tests (assuming unequal variance by default, but can be changed) and returns the results and effect sizes in a tidy dataframe. Beware: It will automatically omit missing values.

Usage

pairwise_t_tests(
  df,
  outcome,
  groups,
  p.adjust.method = p.adjust.methods,
  conf_level = 0.95,
  var_equal = FALSE
)

Arguments

df	A dataframe containing the outcome and grouping variable
outcome	The outcome variable in dataframe
groups	The grouping variable (each distinct value will be treated as a level)
p.adjust.method	The method to adjust p-values for multiple comparison (see p.adjust)
conf_level	confidence level of the interval.
var_equal	a logical variable indicating whether to treat the two variances as being equal. If TRUE then the pooled variance is used to estimate the variance otherwise the Welch (or Satterthwaite) approximation to the degrees of freedom is used.

Value

A tibble containing the results of the t-tests with one test per row, including a column ('apa') formatted for reporting

Examples

pairwise_t_tests(mtcars, wt, cyl)
