Powerbi Desktop and error with R (GGPLOT)

Question

I’m really stuck and I need help.

After installing R 3.5.1, I get this error message in the R views on the Power BI Desktop I was working on earlier.

"Error: package or namespace load failed for 'ggplot2': package 'Scales' was installed by an R version with Different Internals; it needs to be reinstalled for use with this R version."

I’ve already tried:

• reinstall R 3.5.1

• resintalar Rstudio

• reinstall gglar plot2 and scale pack

• reinstall all packages

• reinstall the Powerbi

But it’s not working yet.

Considerations:

• My views were working well before the installation of R 3.5.1

• My views are working correcting on other computers

Any idea?
