ggplot manual is available

Goal 1: ggplot without grid — someone has the post
Goal 2: Modify with no legend
Goal 3: Add x/y labels

Goal 4: Plot SNP panels with multiple samples

Do some researching and found this post is very helpful and can be used as the starting point

Goal 5: save a vector figure, .emf

p <- ggplot (someObject)
usage: ggsave ("someFigure.emf", p)
