The challenge I face is as follow: I have a table such as x | fivenum --------------- ... | (.....) ... | (.....) and so forth.... For each observation x I have generated a vector containing the fivenum estimates. The first challenge is to group my fivenum vectors into groups based on a selection criterion of x, say for 0 < x < 6, all fivenum vectors would be collected in that group. Once all my fivenum vectors are in their respective groups, I wish to generate a b&w plot for each group. How could I possibly do that? Also, what would be the most convenient approach. Looking forward to your suggestions. Many thanks in advance!
