No, I just want to the values for one class nothing applied to them. So for example tapply(x$val, x$label, hist) gives me all kind of stats that can be used for plotting the histogram. But I want to plot the actual histogram for one class. I guess it would be easiest to take your construct and just "echo" the values for a specific class. I hope you understand better what I mean....
