Frequently Asked Questions

Why can’t I load my package? It is listed my config file and I ran rv sync

If you are getting an error like the following:

> library(dplyr)
Error in `library()`:
! there is no package called 'dplyr'
Show Traceback

It is likely because your .libPaths() is not set to the rv library path.

There are a few reasons this can occur:

1. Your .Rprofile is not sourcing rv/scripts/activate.R

   • Run restart R or run source(".Rprofile"). After either, you should see a message containing the following:

     rv libpaths active!
     library paths:
         /Users/rv-user/projects/prism-pkg-pub/rv/library/4.4/arm64
         /Library/Frameworks/R.framework/Versions/4.4-arm64/Resources/library

   • Ensure rv/scripts/activate.R is present in your directory. If it is not, run rv activate and restart R.
   • Ensure source("rv/scripts/activate.R") is present in your .Rprofile. If it is not, add it as the first line

2. You are launching a background job from a subdirectory that does not contain a .Rprofile

   This often occurs when rendering a quarto document. In this case, add a .Rprofile to the subdirectory that sources the project root’s .Rprofile.

   For example, if we want to render a quarto document from two subdirectories inside the project, we’d add a .Rprofile that contains source("../../.Rprofile")

   • Directorymy-project/

     • Directoryscripts/

       • Directoryreports

         • my-report.qmd
         • .Rprofile contains source("../../.Rprofile")
     • Directoryrv/scripts

       • activate.R
     • .Rprofile contains `source(“rv/scripts/activate.R”)
     • rproject.toml
