R Documentation

Power simulation

Description

Using the R packages metafor and pwr to calculate a powersimulation for a given dataset and specified parameters. The results are plotted using ggplot2.

Usage

powersim(yi, vi, measure, d, n, pval = 0.05)

Arguments

`yi`	A `string` of the variable which holds the vector of length k with the observed effect sizes or outcomes in the selected dataset (d)
`vi`	A `string` of the variable which holds the vector of length k with the corresponding sampling variances in the selected dataset (d)
`measure`	A character string indicating underlying summary measure. Depending on the type of measure the input data for fitting needs to be transformed and backtransformed later.
`d`	A `string` representing the dataset name that should be used for fitting.
`n`	A `Integer` representing the sample size which should be used for the power simulation.
`pval`	A `Numeric` representing the significance level which should be used for the power simulation.
