Since installing R 3.5.0 I have a problem installing/updating/building packages that go into the library path of my user account. I give some detailed error messages below. Any help appreciated.
To summarize, the warnings show a split in the library path at the space in my username (I use Windows10). (I also notice the use of both "/" and "\" but do't know what that means.
Warning: invalid package 'C:\Users\Neil' Warning: invalid package 'Caithness\AppData\Local\Temp\RtmpaangbE/downloaded_packages/stringi_1.2.2.tar.gz'
My library paths are:
> .libPaths()  "C:/Users/Neil Caithness/Documents/R/win-library/3.5"  "C:/Program Files/R/R-3.5.0/library"
Detailed messages below. Installing devtools seems to work, but stringi and many others don't.
(PS. Edit. It's not the library path that causes the problem, but the path to the downloaded source package. This is a .gz file for stringi, but a .zip file for devtools. Does that mean something? I also get the same problem when I try to build any of my own packages.)
(PPS. Simply reverting to previous versions of R doesn't solve the problem (3.4.4, 3.4.0) but I know that up until about last week it was fine. So at the moment I don't know what changes could have caused this, or what to do about it? )
