Dear R help, I am new to ggplot so I apologize if my question is a bit obvious.
I would like to create a plot where a compare the fraction of the values of a variable called PASP out of the number of subjects, for two groups of subject codified with a dummy variable called SUBJC. The variable PASP is discrete and only takes values 0,4,8.. My data are as following: PASP SUBJC 0 0 4 1 0 0 8 0 4 0 0 1 0 1 . . . . . . I would like to calculate the fraction of positive levels of PASP out of the total number of observations, divided per values of SUBJ=0 and 1. I am new to the use of GGPlot and I do not know how to organize the data and what to use to summarize these data as to obtain a picture as follows: I hope my request is clear. Thanks for any help you can provide.
