install.packages doesn't produce warnings unless qualified with utils::

Hi all,

Assuming this is an R core issue:

tryCatch(install.packages("clipr", repos = "bullshit"), warning = function
(w) cat("got a warning"))
Warning in install.packages :
  unable to access index for repository bullshit/src/contrib:
  cannot open URL 'bullshit/src/contrib/PACKAGES'
Warning in install.packages :
  package ?clipr? is not available (for R version 3.4.3)
Warning in install.packages :
  unable to access index for repository
bullshit/bin/macosx/el-capitan/contrib/3.4:
  cannot open URL 'bullshit/bin/macosx/el-capitan/contrib/3.4/PACKAGES'

In other words, lots of warnings, but none are caught.

It works if you use the fully qualified version in utils:

tryCatch(utils::install.packages("clipr", repos = "bullshit"), warning =
function (w) cat("got a warning"))
got a warning

Any ideas?
Cheers,
David

Using R-3.4.3 on 64-bit Ubuntu throws and catches the warning.

R> tryCatch(install.packages("clipr", repos="w"), warning=function(w)
cat("got a warning!\n"))
Installing package into '/home/josh/R/library'
(as 'lib' is unspecified)
got a warning!
My guess is that something (a package, console, etc) is masking
utils::install.packages().
