Subject: a replace for subset
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.Elahe
