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

Installation

To install the released version:

> install.packages("Durga")

To install the development version:

> install.packages("devtools") # If not already installed> devtools::install_github("KhanKawsar/EstimationPlot", build_vignettes = TRUE)

Usage

Read the paperKhan & McLean(2023) for a detailed description of the package. Once Durga isinstalled, you can read the vignette namedIntroduction to Durga for a shorter introduction to usingDurga, complete with examples and code.

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)
