Use of custom packages

[rhs94]

Hi
I did not understooth where I should run this and how:
$ Rscript -e "devtools::install('path/to/package', lib = '/app/library')"

Is it in the command prompt, in the package.txt file, in the R script for the ui and server?
And what do I need to write instrad of 'path/to/package'? Which path should it be?

I really hope someone can help! Thanks in advance!

I'm not a developer, but I have encountered this problem and you can do this by opening dist/R-Portable/App/R-Portable/bin/ R.exe and then installing your own custom package
