could not find function "ggplot"

[flik]

Thank you for your feedback

@andresrcs

Also, there is some discrepancy here, you said that you have R 3.5.1 but the message says that you have installed ggplot2 under R 3.5.3, could you clarify?

When I open R, there is written: R version 3.5.1 (2018-07-02) -- "Feather Spray" [...]. For this reason, I don't know why I get the error "package ‘ggplot2’ was built under R version 3.5.3". It is one of my doubts.
