R Visual Rcpp package error

[dpombal]

Hi, all

I was using several custom visuals using R using R 3.4.2 however after upgrading to latest R 3.5.1 I find both custom  R visuals and basic Object visuals using R start failing (even after upgrading packages to R 3.5.1 compatibility)

1st Error on R Visual

R Code

library(ggplot2)
t<-ggplot(dataset, aes(ID, Promedio)) + geom_point(aes(color=factor(Year))) + facet_wrap(~Year)
#Cambiando los colores
t + scale_color_manual(values=c("red","black","green"))

Error trace 1

Error Message: Error in R script .
Error: package or namespace load failed for 'ggplot2':
 package 'Rcpp' was installed by an R version with different internals; it needs to be reinstalled for use with this R version
Ejecución interrumpida

Most annoying part is that previous code works in RStudio!! I have Powerbi--Z Options-->R pointing to my R version 3.5.1

Same code in R Studio works OK, without errors

I had yesterday the same problem. Only reinstalling (or even go back to older versions) did not help.

Only after I deleted the libraries in "<user>/documents/R" and in "<user>/library"  and reinstalled R and installed the packages I needed, the problem was solved.

I think mixed package versions in <user>/library did give the problem for me. I did not know that packages were also in that directory. Only uninstall R en delete "<user>/documents/R" was not enough.

The newest version of PowerBi and R (3.5.1) are now working for me.
