Error: package or namespace load failed for 'ggplot2': package 'ggplot2' was installed before R 4.0.

[webportal]

I'm really stuck and need some help.

After installing R 4.0.2, I'm getting this error message on R visualizations in Power BI Desktop which were previously working

"Error: package or namespace load failed for 'ggplot2':
 package 'ggplot2' was installed before R 4.0.0: please re-install it.
 Execution halted"

I already tried to:

reinstall R 4.0.2reinstall RStudio

reinstall ggplot2 

reinstall all packages

reinstall Power BI Desktop. My version is August-2020

Still it does not work.

Considerations:

My visualizations were working well before I installed R 4.0.2My visualizations are working well on other PCs

When I run the code on RStudio I don't get any error

Any thoughts?

Have folks discovered other workarounds to the error? It's a bummer to have to remove old instances of R to get ggplot2 to work in Power BI. Particularly since there are some visualizations in PBI that only work on some of the older instances, and some on the newer instances.

I just changed it to my old version and it worked.

Hi @webportal 

Try below solution:

Find the root folder of R :

Run it and input : 

install.packages("ggplot2")

then enter "yes>yes.." until finished.

Problem is solved after DELETING old libraries inside

"<user>/documents/R" and in "<user>/library"

You can see in .libPaths 2 routes but....PowerBI also uses...  "C:\<user>/library"  ....remove old ones from here

• "C:\<user>/documents/R"
• C:\Program Files\R\R-4.0.2\library

Actually, I had also tried that. I had conflicting versions of packages, and deleted all the old ones and reinstalled everything again to 4.0.2.
It didn't work, so I uninstalled all 4.0.2 again, including R Gui and R Studio and reinstalled all 3.6.3. and it finally worked!
