Creating a Power BI Custom Visual R HTML internalSaveWidget(p, 'out.html') fviz_pca_var

[anaid]

Hi all, 

I would like to create a visual of a Principal Component Analysis using this fviz_pca_var function from this library factoextra.

I thought that p here internalSaveWidget(p, 'out.html') could be the output of fviz_pca_var function, but it is not working.

I getting this error:

Error Message:
