The problem, as diagnosed by Maria in the first post of the thread, is
that the user home directory as known to R is stored in the ANSI
encoding instead of UTF-8, despite the session charset should be UTF-8
as Maria's Windows is sufficiently new [*]. As soon as any bit of R
tries to perform an encoding conversion using this path (for example,
file.exists() converting it from UTF-8 to UCS-2 in order to interact
with Windows filesystem APIs), the conversion fails. Since tcltk2 uses
file.exists('~/...') in its .onLoad, the package and any of its hard
dependencies are now broken.

Normally, this path is determined automatically to be something like
C:\Users\username\Documents. With OneDrive taking over, it turns out to
be something else and for some reason in the wrong encoding (ANSI but
marked as native == UTF-8).

The function that determines this path lives in src/gnuwin32/shext.c
(char *getRUser(void)). It starts by looking at the environment
variable R_USER, which is why in order to override OneDrive, the user
has to set it first (in the command line or system settings). If that
fails, R tries the environment variable HOME (which is usually set on
Windows, isn't it?), consults SHGetKnownFolderPath(FOLDERID_Documents)
(which returns the result as a wchar_t[] to be manually converted to
UTF-8 by R), consults a few more environment variables, and finally
tries to use the current directory. There is likely no easy way to use
`subst` to give a different home drive to R.

If I set %HOME% or even %R_USER% to a non-ASCII path without setting up
OneDrive, R works normally, so getenv() must be able to return
UTF-8-encoded variables. I don't see how ShellGetPersonalDirectory()
could fail in this manner. My remaining hypothesis is that OneDrive
somehow causes getenv("HOME") to return "C:\\Users\\marga\\OneDrive
- Fundación Universitaria San Pablo CEU\\Documentos" in ANSI instead of
UTF-8.

If anyone here has OneDrive set up in this manner and can debug R,
a trace of what getRUser() actually does would be very useful.

Re: [R] Problem with R coding

[Iris Simmons]

Hi Maria,


I had something similar on my Windows work laptop at some point where the
home directory was something containing non ASCII characters. The easy
solution is to copy said directly from the file explorer into
utils::shortPathName, and then set that as the home directory. In my case,

> writeLines(utils::shortPathName(r"(C:\Users\iris\OneDrive - Organization
Name Non ASCII\Documents)"))
C:\Users\iris\ONEDRI~1\DOCUME~1

and then in the control panel, then user accounts (twice), then Change My
Environment Variables, enter the variable name HOME and the directory that
was produced by R. Now the HOME directory contains all ASCII characters so
everything works as expected.


I hope this helps!

Re: [R] Problem with R coding

[CALUM POLWART]

That's almost certainly going to be either the utf-8 character in the path
OR the use of one drive which isn't really a subfolder as I understand it.

When I've had these issues in the past, I've been able to mount a drive
(say U:/ ) which sites further down /up the folder tree so that R just
called "U:/RCodeFolder/Rfile.R"

Is that possible with an C drive?

Dear Maria,

I'm sorry for somehow completely missing the second half of your
message where you say that you've already tried the workaround.

Glad to know the workaround helped. It sounds like your Windows
10 is set up in a user-hostile way.

It may help to visit the Windows Security settings and make an
exception for C:\Users\marga\Desktop\R-4.3.3\bin\R.exe. An approximate
instruction can be found at
, but it
might be the case that your university IT must take a look at it before
allowing you to run R on your computer.

Feel free to disregard this advice if someone with more Windows
experience shows up.

We've seen this problem before:
https://stat.ethz.ch/pipermail/r-help/2023-December/478732.html

The workaround that should help is to set the R_USER environment
variable to C:\Users\marga before launching R.

Please let me know if you're willing to debug R. (This will likely
involve compiling R from source with debugging symbols enabled and
stepping through the code.) There are no places in the Windows code
where R gets the conversion obviously wrong. I don't have OneDrive and I
wasn't able to convince R to return an invalid R_USER path without it.
I'm halfway convinced this is due to a bug in OneDrive itself.

What should I do?

Hello,

First of all, try running Rgui only, no R.exe CMD. Just Rgui.exe or
C:\Users\marga\Desktop\R-4.3.3\bin\Rgui.exe
Then, in Rgui, try loading Rcmdr

library(Rcmdr)


Also, do you have R in your Windows PATH variable? The directory to put 
in PATH should be


C:\Users\marga\Desktop\R-4.3.3\bin

so that Windows can find R.exe and Rgui.exe without the full path name.

Hope this helps,

Rui Barradas
