This looks about right. On R in the terminal the warning is thrown. In
Rstudio I have the problem, and:

 > getAnywhere('install.packages')
2 differing objects matching ‘install.packages’ were found
in the following places
  package:utils
  namespace:utils
Use [] to view one of them

And the version in package.utils looks like:

function (...)
.rs.callAs(name, hook, original, ...)

OK, so an RStudio issue. Indeed, this looks like the problem:

https://github.com/rstudio/rstudio/blob/master/src/cpp/r/R/Tools.R

There, callAs is defined as running a function with error handlers which
use `cat` to reprint warnings.

Thanks!

[Rd] Unclosed parenthesis in grep.Rd

[Hugh Parsonage]

Lines 129-131:
\code{grep(value = FALSE)} returns a vector of the indices
of the elements of \code{x} that yielded a match (or not, for
\code{invert = TRUE}. This will be an integer vector unless the input

There should be a closing parenthesis after \code{invert = TRUE}
