Plots (ggplot2) in my R markdown slides (xaringan) error when i share in R pubs or just html file

Question

I'm trying to share mi homework in r markdown slides (with xaringan) through r pubs o just sharing the html file but i realized that the plots looks like: error that doesn't exist in my local machine.

i'm not sure why, but renderized just the r markdown has html works fine.... i guess that there could be something in the script. Also, i leave here the configuration of r chunks that deploy the plots (ggplot)

Thanks in advance
