This is not the place for tutorials (although I recognize that many
responses and discussions do intersect tutoriality).
If you do a web search on ggplot tutorials you will find many good ones. Or
go to the RStudio website which links to resources, including Hadley
Wickham's book, which is probably the most authoritative. Incidentally,
ggplot is based on Leland WIlkinson's book "The Grammar of Graphics" that
provided the blueprint for Wickham's software (his PhD project at Iowa
State I believe).
