Proposed addition to check() [using .libPaths() in .Rprofile]

[csgillespie]

In my .Rprofile I've recently added .libPaths("/path/")

Interestingly, this usually works, but occasionally it doesn't. For example,

• RStudio console and terminal picks up path/
• Running a check package works
• Running a build package doesn't

Likewise, a standard R CMD build XXX doesn't work.

Proposal: have check() detect and warn as necessary. Happy to attempt a PR.

The reason I have it in my .Rprofile was due to littler ignoring .Renviron files (eddelbuettel/littler#64)

Wow, interesting. I wonder if this should also be reported as a bug in R. For future records, what version of R are you observing this on?

There's a couple of screenshots as well.

And just to be 100% on the same page, will running that devtools::document(...) from the RStudio Console also fail?

[csgillespie]

• devtools::document() works in both the Rstudio console and RStudio terminal.
• Check package (CTRL + Shift + E) on RStudio also works

Likewise, a standard R CMD build XXX doesn't work.

I'd like to confirm this in order to rule out that it's a devtools bug. As a test trying to figure out what's going on, I've added the following to my ~/.Rprofile:

system2("echo", args = "[system] .Rprofile ...")
.libPaths(c(tempfile(), .libPaths())
system2("echo", args = c("[system] .libPaths: ", .libPaths()))
system2("echo", args = "[system] .Rprofile ... done")

to confirm that R CMD build does indeed source .Rprofile:

$ R CMD build listenv
[system] .Rprofile ...
[system] .libPaths: /home/hb/R/x86_64-pc-linux-gnu-library/3.5 /usr/local/lib/R/site-library /usr/lib/R/site-library /usr/lib/R/library
[system] .Rprofile ... done
* checking for file ‘listenv/DESCRIPTION’ ... OK
* preparing ‘listenv’:
* checking DESCRIPTION meta-information ... OK
* installing the package to build vignettes
* creating vignettes ... OK
* checking for LF line-endings in source and make files and shell scripts
* checking for empty or unneeded directories
* building ‘listenv_0.7.0-9000.tar.gz’

So, it's not that ~/.Rprofile is skipped by R CMD build itself at the top level. However, it could still be that there are some internal system calls that R CMD build performs that runs with --vanilla or similar.

One further step forward.
