Hello,
I am a student in the UK and use RStudio for my coursework and research
projects. I have been using RStudio on my personal laptop for over nine months
without any issues.
Recently, I was provided with an NHS organisation laptop for my project, and I installed
RStudio on that device as well. However, I am now encountering a problem where I am
unable to install any packages. RStudio consistently returns the error message:
"cannot connect to URL."
Both the IT team and I have been trying to identify and resolve the issue, but
we have not yet been able to determine the cause.
I would greatly appreciate any guidance or assistance you can provide in
resolving this issue. Thank you for your time and support.
Thanks and regards,
Shilpa

Hello,
It's difficult to say what is going on but if you open a Terminal window
(or cmd in Windows) and run
Rscript -e "install.packages('pkg_name', repos =
'https://cloud.r-project.org/')"
does it work?
Can you run
sessionInfo()
and post its output?
Hope this helps,
Rui Barradas
