Hi, I have a data set (mydata), which a part of this is like the following:
'data.frame': 36190 obs. of 16 variables: $ RE : int 38 41 11 67 30 18 38 41 41 30 ... $ LU : int 4200 3330 530 4500 3000 1790 4700 3400 3640 4000 ... $ COUNTRY : Factor w/ 4 levels "DE","FR","JP", "FR"… $Light : Factor w/2 levels "ON","OFF","ON", …. $OR : Factor w/2 levels "S","T","S",…. $PAT : Factor w/3 levels "low", "high", "middle",…. Now I want to plot RE vs LU with ggplot2 for all the possible cases, I know how to do subsetting for the data but I want to know is there any shorter way to do that? For example I want to have a plot for RE vs LU for (COUNTRY= FR, Light=off, OR=S, PAT=low) and one for (COUNTRY= FR, Light=on, OR=S, PAT=high) and …., as you see doing subset is time consuming, is there any other way? Thank you for any help.
