[R] GGPlot plot

[Rui Barradas]

Hello,

Your request is not entirely clear.

What kind of a graph do you want? A bar graph with a bar of the fraction 
of positive levels of PASP per each level of SUBJC?
You need to be more specific.

Also, please post data like this:

# post the output of this command in your next mail
dput(head(data, 30))


Hope this helps,

Rui Barradas
