Purpose

Below instructions gives you the possibility to configure a custom library path so you can install/load R packages not included in the standard configuration of R in the Secure Citrix Environment (securemints).   

How To 

You need to create a custom .Renviron file and R-Libs folder in your Home Drive (U) which will be used to install/save all your custom R packages.  You will only need to follow the instructions once 

• Login to Securemints on https://securemints.medschl.cam.ac.uk  with your SDHS account
• Open your Home Drive U
  • Navigate to My Documents
    • Create R-Libs folder
  • We have now created U:\Documents\R-libs path
    
    
• Open Notepad++ and add
  • R_LIBS_USER='U:/Documents/R-libs'  
  • File -> Save As
    • Save in: U:  (file should be saved in the root of Home Drive (U)
    • Filename: .Renviron 
    • Save as Type: All files (no text, file should have no extension)
• Restart R Studio

Check if new path is now showing in R Studio (run below command to show the paths).

• .libPaths() 

Try to install a package and run it 

• install.packages("haven")

Now try to run it

• library(haven)
• it should return > 

Logoff / Logon again in SDHS Citrix Environment so we can check the paths and installed libraries are still there.
