repeated_measures_anova function

Repeated-Measures ANVOA

Conduct a repeated-measures analysis of variance (ANOVA). This analysis will be appropriate for within-subjects experimental design.

repeated_measures_anova(
  data = NULL,
  p_col_name = NULL,
  measure_vars = NULL,
  histograms = TRUE,
  round_w = 2,
  round_epsilon = 2,
  round_df_model = 2,
  round_df_error = 2,
  round_f = 2,
  round_ges = 2
)

Arguments

• data: a data object (a data frame or a data.table)
• p_col_name: name of the column identifying participants
• measure_vars: names of the columns containing repeated measures (within-subjects variables)
• histograms: logical. If histograms = TRUE, histograms of the repeated measures will be plotted. If histograms = FALSE, no histograms will be plotted.
• round_w: number of decimal places to which to round W statistic from Mauchly's test (default = 2)
• round_epsilon: number of decimal places to which to round the epsilon statistic from Greenhouse-Geisser or Huynh-Feldt correction (default = 2)
• round_df_model: number of decimal places to which to round the corrected degrees of freedom for model (default = 2)
• round_df_error: number of decimal places to which to round the corrected degrees of freedom for error (default = 2)
• round_f: number of decimal places to which to round the F statistic (default = 2)
• round_ges: number of decimal places to which to round generalized eta-squared (default = 2)
