If you encounter error in installing "tidyverse" package on R, the solution is on the terminal install first the two packages (libfribidi-dev and libharfbuzz-dev):
# apt-get install libhartbuzz-dev
# apt-get install libfribidi-dev
After installing these two packages, on the R cli, install the "tidyverse" package:
> install.packages("tidyverse")
To load the "tidyverse" library on R, issue the command:
library("tidyverse")
This works on Ubuntu 20.04.
