Switching R versions in Windows
In order to facilitate reproducible data analysis, researchers should use the same version of a software package to conduct analyses throughout a study. The same holds true when using programming languages like R. Thus, if you maintain several versions of R (i.e 3.6, 4.1) on your computer then you can switch between the versions used. Futher, some packages may only work with an earlier version of R, therefore necessitating switching between versions.
