[R] a replace for subset

[chalabi.elahe at yahoo.de]

-Thank you James, well the problem of my type of data is that there can be many possible subsets and therefore plots, and I want to automatically generate them, and facet_wrap does not give me all the possible cases

Would facet_wrap or facet_grid give you what you want?

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?
