shivam commented on ARROW-16787:
--------------------------------
My current setup is as follows:
# Load all the relevant R Packages except "arrow"
# Import all the relevant Python Modules including "pyarrow"
# Load R package "arrow"
As I mentioned originally, importing python module before loading R package
does not cause any observable problem.
I have done some basic testing and even if I *attach and detach* R package
"arrow" before import of python "pyarrow", the system throws error. I did try
to cleanly detach all additional packages that were "{*}loaded via a namespace
(and not attached){*}" in R sessionInfo() output. However, it looks like the R
package, on detach, leave behind some namesapces /modified system state that is
not same as what it was before the package was attached.
Sadly, that is the extent of my understanding of R internals /namespaces and I
was unable to go forward.

> Key: ARROW-16787
> URL: https://issues.apache.org/jira/browse/ARROW-16787
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python, R
> Affects Versions: 8.0.0
> Reporter: shivam

> Labels: windows
> Attachments: Reticulate-Arrow-Pyarrow.Rmd,

> Sorry, I am new here and prepared the issue report based on GitHub markdown
> syntax.
> And I am unsure about assigning priority as "Major", please change it to
> appropriate level.
> I have attached an RMD File (& its HTML output) which can be knitted in R and
> shows the problem.
>
> - Details:
> - Within RStudio using Reticulate package, and without any virtual
> environment
> - If R arrow Package is attached before import of Python pyarrow module,
> then import fails.
> - If R arrow Package is either not attached or attached after the import of
> Python pyarrow module, then there seems to be no problem. Both R and Python
> are able to read feather files.
>
> Please send a message if any information is missing or if more clarification
> is required.
> Thank You
