I\'ve found a number of questions related to this warning when installing or updating packages in R/RStudio, but none seem to completely match my situation:

Answer 1

My original reply is below, but I've subsequently found a better solution.

Execute the following line:

Trace(utils:::unpackPkgZip, edit=TRUE)

Note that there three colons in there, not two.

Then edit line 142, from Sys.sleep(0.5) to: Sys.sleep(2.0), and click to save the edit (the line number may vary slightly). Unfortunately this does not hold across R sessions, but it only takes 10 seconds to do this, and then you can install packages for the current session to your heart's content.

Original answer:

I ran into the same problem at work. I was able to use Sheldon's suggested approach, but as noted that can get tedious quickly. As an alternative, I found I could go to the location of the downloaded zip file(s) in my temp directory (as reported by install.packages), unzip the file or files (there will be multiple zip files if there are dependent packages), and then move or copy all the unzipped directories straight into my R\win-library\3.4 directory. This isn't a whole lot of fun either, but I find it to be less painful than stepping through the debugger, per Sheldon's method, especially when multiple dependencies are involved and also have to be installed.
