How to launch GUI [R for BE/BA]

Hi Elena777

Supposed that you have already installed bear correctly. After opening RStudio (or R console), please type library(bear), and then type go(). Now you have GUI of bear. Click the pop-down menu under I want to do: (the second item of the left panel) and select sample size estimation. Another GUI will pup-up. This GUI is for sample size estimation. However, I would like to strongly recommend that you should consider using PowerTOST package for sample size estimation.

[edited] PS. if you like to know how to install bear or how to use PowerTOST, please search the Forum.

All the best,
