This issue only came up after I installed R3.5.2. Never had any problems with previous installations. So it is likely a bug in the current version. Any suggestions what to do now?

You could delete your 3.5 personal package library (using the File Explorer with Run as Admin if necessary) and re-install your packages without running as Admin. If that does not work try uninstalling R and re-installing 3.5.1. On December 22, 2018 8:16:11 PM PST, Janh Anni <annijanh at gmail.com> wrote:>This issue only came up after I installed R3.5.2.

I tend to think that Jeff is right and you, Janh, *have* changed something on your Windows box, or inadvertently during installation of R. I've tried our Windows Server installation (where I consciously do install things as admin for all win server users to use it), and I can install packages fine as simple user -- into the personal library that is created after asking for user confirmation. Also, given the number of R users and the (unfortunately still) high percentage of Windows users among them, I strongly assume we would would have heard of it if this was a common problem.. (But then I may be wrong if the Windows users are "slow" to update their R version) Martin Merry Christmas! > On December 22, 2018 8:16:11 PM PST, Janh Anni > <annijanh at gmail.com> wrote: >> This issue only came up after I installed R3.5.2.

Hello Jeff, Martin, I deleted 3.5.2 as suggested and tried 3.5.1 but still had the same problems. I still couldn't use read.table to load a data file and still had an error message when I tried to install a package. Usually after installing a new version of R, I would go to the R icon on the desktop, right click on it, click on Properties and then specify the folder that contains my data files in the "Start in" box, so that R automatically has access to my data files. Could that possibly be causing problems with these newer versions of R? Also, there?s never a prompt during the installation to Run as Administrator, so that could not possibly be the cause I also just tried Version 3.4.4, and had no problems whatsoever either with using read.table to load data files or downloading packages. So there must be some changes from version 3.5 onward that created the issues. Hopefully this will be looked at more closely by the team with a view to resolving the issues Thanks, Janh On Sun, Dec 23, 2018 at 1:31 AM Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote:> You could delete your 3.5 personal package library (using the File > Explorer with Run as Admin if necessary) and re-install your packages > without running as Admin.
