Do I need to install.packages every time I use Rscript in linux command line?

Question

I am using bio3d package in R and use Rscript to run it in the Linux command line. Do I need to install packages every time I run the R file or only library it after the first time of installation like what we used to do in the Rstudio?

Thank you.

Answer 1

You only need to install a package once per installation of R/major R version. (A "major version" of R refers to the second digit of the version number, eg you need to re-install packages when moving from version 3.5.2 to 3.6.0 or from 3.6.1 to 4.0.1, but not when moving from version 4.0.0 to 4.0.1.)
