Issues with R3.5.2

you can just use libpath to specify which packages to use instead of
deleting libraries

also use sessionInfo () at the beginning to see what is loaded

Yes, that would be the personal library.

There is one question in the installer that asks if you would like to
create a personal library... I have always said yes, but I could imagine
that saying no could lead to problems.

I am sorry I forgot to mention - I just looked in the
Documents\R\win-Library directory and only found folders for previous R
versions, specifically R3.0, 3.1 and 3.4.  So I must have deleted the
R3.5
folder as you initially advised or it was removed during the
un-installation.  Unless I am misunderstanding what you mean by the
R3.5
personal package library?  Thanks again

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?

No.

Also, there?s never a prompt during the
installation to Run as Administrator, so that could not possibly be

the

cause

Yes, you have to go out of your way to Run As Administrator (RAA).
However, regardless of how you initially encountered a problem, once

you

did that there could be any number of files contaminated with

permissions

issues.

Specifically, I said to delete your 3.5 personal package library, but

your

description is not specific so I suspect you may not have done that.
However, any file modified by you intentionally or not while using

RAA

could be causing your problems now, so now it is up to you to find

those

files somehow.

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

I doubt the "team" will spend much time looking at this based on your
descriptions so far. They need something reproducible, and the fact

that

you already used RAA to "fix" the problem makes anything you did

prior to

that almost impossible to reproduce.

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.

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?

That normally only occurs if you have at some time used

elevated

permissions, beyond which point you fall into a downward spiral

of

more

permissions trouble. You are apparently already in trouble,

whether

it was

of your own making or due to a bug in the installer.

Also, never update the system R package library... always use a

personal

library.

Hi Jeff,

No, during the installation, there was not an option to Run as
Administration.  But *after *installation, I found that if I

selected

Run
as Administrator, then I could install packages using

install.packages

as
usual without problems.

Thanks

Did you by any chance use Run As Administrator to install R?

If

so

then

you need to uninstall it and delete all files created by it

(e.g.

Documents/R/win-lib/3.5/) and re-install using UAC as

prompted.

Dear R Experts,

I use Windows 10 and just installed the new R version,

R3.5.2

but

when

I
tried to load a data file using read.table, I got an error

message

like

this:

*Error in file(file, "rt") : cannot open the connection*
*In addition: Warning message:*
*In file(file, "rt") :*
*  cannot open file 'StreamPCB.dat': No such file or

directory*

Also, I couldn't install packages using install.packages as

usual,

unless I
run R as Administrator

I wonder if anyone else had the same issues and any

suggestions

how

to

fix?

Thanks a lot
Janh
