aov_ss: Sex Specific One way ANOVA From Summary statistics

In TestDimorph: Analysis of the Interpopulation Difference in Degree of Sexual Dimorphism Using Summary Statistics

Sex Specific One way ANOVA From Summary statistics

Description

Calculates sex specific one way ANOVA from summary statistics.

Usage

aov_ss(
  x,
  Pop = 1,
  pairwise = TRUE,
  letters = FALSE,
  es_anova = "none",
  digits = 4,
  CI = 0.95
)

Arguments

x	A data frame containing summary statistics.
Pop	Number of the column containing populations' names, Default: 1
pairwise	Logical; if TRUE runs multiple pairwise comparisons on different populations using Tukey-Kramer's post hoc test, Default: TRUE
letters	Logical; if TRUE returns letters for pairwise comparisons where significantly different populations are given different letters, Default: FALSE'
es_anova	Type of effect size either "f2" for f squared,"eta2" for eta squared, "omega2" for omega squared or "none", Default:"none".
digits	Number of significant digits, Default: 4
CI	confidence interval coverage takes value from 0 to 1, Default: 0.95.

Details

Data is entered as a data frame of summary statistics where the column containing population names is chosen by position (first by default), other columns of summary data should have specific names (case sensitive) similar to baboon.parms_df

Value

Sex specific ANOVA tables and pairwise comparisons in tidy format.
