could not find function "ggplot"

@flik

there is no package called ‘colorspace’

That error message is different, you have to install the missing dependency

install.packages("colorspace")

@flik

In addition: Warning message:
package ‘ggplot2’ was built under R version 3.5.3

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?
