R - How to set the path of install.packages() for shiny server ? - Ubuntu

Question

For my system: Ubuntu 12.04 and R 3.03, whenever I install a custom package in R via

>install.packages(         


        

Answer 1

I would propose a different approach.

The problem is that shiny-server cannot find the packages that you install because it runs them as a different user which is called shiny. This user is created upon installation of shiny-server

The easiest (and safest IMHO) way to solve this is to just install the packages as the shiny user, using the following steps.

1. Set a password for the user using sudo passwd shiny, now enter and confirm a password of your choosing.
2. Switch to the shiny account using: su - shiny
3. Call up R using $ R (without sudo)
4. Install the required packages, in this case: `install.packages("shinydashboard")

Note that if you have rstudio-server installed on the same machine then you can perform steps 2-4 using that interface. Simply go the same domain/ip and use :8787 for the rstudio-server interface instead of :3838 for shiny-server.
