Description

These movies are animations used to illustrate key statistical ideas. They are produced using the rpanel-package, which has BWidget as a system requirement. BWidget is included in the R installers for Windows and macOS. For other platforms please see Section 1.1.7 of Writing R Extensions for installation advice.

Details

When one of these functions is called R opens up a small parameter window containing clickable buttons that can be used to change parameters underlying the plot. For the effects of these buttons see the documentation of the individual functions.
