Durga: An R package for effect size estimation and visualisation

Effect size estimation and plotting is a component of estimation statistics. Durga is an R package that aims to simplify sophisticated plotting of estimated differences in group means, which is an important part of communicating estimation statistics.

Usage

Read the paper Khan & McLean (2023) for a detailed description of the package. Once Durga is installed, you can read the vignette named Introduction to Durga for a shorter introduction to using Durga, complete with examples and code.

RShowDoc("Durga-intro", package = "Durga")

# Display the vignette in the help window pane

A minimal example using constructed data:

  n <- 100
  df <- data.frame(val = c(rnorm(n), rnorm(n, mean = 1)),
                   group = c(rep("Control", n), rep("Group", n)))

  d <- DurgaDiff(df, data.col = "val", group.col = "group")
  # or equivalently
  d <- DurgaDiff(val ~ group, df)
  DurgaPlot(d)
