SampleSizeR: Calculate sample sizes within completely randomized design (CRD)

SampleSizeR is an interactive web apps with R (shiny app) to calculate sample size based on power analysis for confirmatory experimental designs. It has been initiated by the Applied Statistics group of the Department of Mathematics at the University of Zurich. The aim of the online resource is to help scientists to better plan their experiments. The default values and settings are tailored to experiments in animal or preclinical research.
