installing package is failing with: Error in if (file.exists(dest) && file.mtime(dest)

Question

I am trying to install rethinking

httr::set_config( httr::config( ssl_verifypeer = 0L ) ) 
with_config(use_proxy("http://myco.com:5555"), install_github("rmcelreath/rethinking", lib ="C://TOOLS/R-3.4.0/library"))

I get the error messages:

Downloading GitHub repo rmcelreath/rethinking@master
from URL https://api.github.com/repos/rmcelreath/rethinking/zipball/master
Installing rethinking
Error in if (file.exists(dest) && file.mtime(dest) > file.mtime(lib) &&  : 
  missing value where TRUE/FALSE needed
Error in if (file.exists(dest) && file.mtime(dest) > file.mtime(lib) &&  : 
  missing value where TRUE/FALSE needed

some info on my versions:

> packageVersion("devtools")
[1] ‘1.12.0’
> packageVersion("httr")
[1] ‘1.2.1’
> R.Version()$version.string
[1] "R version 3.4.0 (2017-04-21)"

Can you advise how to get the install to work?

Thank you.

++++++++++++++ WHEN I RUN TRACEBACK() I get

           loaded = pkgs.loaded, check.rows = TRUE, stringsAsFactors = FALSE)
       packages[order(packages$name), ]
   })()

What's the `traceback`? What function is causing the error? Run `debugonce` on that function and figure out which of the conditions is failing and see if you can't suss out why — MichaelChirico, May 18 '17 at 17:52
so debugonce(with_config(use_proxy("http://myco.com:5555"), install_github("rmcelreath/rethinking", lib ="C://TOOLS/R-3.4.0/library")))? — user3022875, May 18 '17 at 18:50
@user3022875 This seems to be a general bug with 3.4.0. under windows. Try reinstalling the patched version, see if that helps.. https://cran.r-project.org/bin/windows/base/rpatched.html — Buggy, May 19 '17 at 14:10
@user3022875 I have posted the comment as an answer for future reference, if somebody else find themselves in the same predicament. Can you checked it as answered? — Buggy, May 22 '17 at 06:06
The idea of the patched version is that it is being updated almost every day. So, _Can't believe, its just patched today_ is not really true. — MS Berends, May 22 '17 at 10:07
I might also happen that you can't view the help pages of some packages. That's fixed with the patched version too. — MS Berends, May 22 '17 at 10:13

This seems to be a general bug with 3.4.0. under Windows.

Update: R 3.4.1. has been released. This might fix your problem as well. https://cran.r-project.org/bin/windows/base/

YOU, are amazing. Indeed an error of 3.4.0. I hope you get your checkmark; I'll just give you an upvote :) – MS Berends May 22 '17 at 10:08
Yes, thanks. For the record, [here's the note](http://developer.r-project.org/blosxom.cgi/R-devel/NEWS/2017/04/29#n2017-04-29) mentioning the bug fix. – Josh O'Brien May 24 '17 at 04:05

I have updated the devtools package to the last one v1.13.2 and I avoid this kind of error when you are trying to install new packages. And I dont' need to install another R version like 3.4.1.

Some info on version:

packageVersion("devtools")

[1] ‘1.13.2’

packageVersion("httr")

[1] ‘1.2.1’

R.Version()$version.string

[1] "R version 3.4.0 (2017-04-21)"

Desinstalling and reinstalling R3.4.0 has solved the problem for me. (I have to use R3.4.0 for external reasons, but it is probably a better idea to install a later version, cf mail from Uwe Ligges from the R-Core team https://www.mail-archive.com/r-help@r-project.org/msg243256.html )
