R script on PowerBI Online does not work !

Hi!
  I've created a Sentiment Analysis for to study the product's amazon reviews for each product that show the last 10 reviews, text analysis and the average score.

It works on desktop but if i publish on PowerBI Online shows me errors:

I suppose in the PowerBI servers miss many package of R.
What shall i do?
Hoping to find a solution,
