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

Hi,

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.

r linux command line

You should only need to install a package one-time unless you are doing it on a RAM disk or some non-persistent storage.

Are you loading the library in your R file? I assume bio3d package is installed in your personal space?
