Hi Jonathan, A couple pointers that can make things simpler when working with lattice graphics: 1. put your data into 'long format': x, y, group <--- the reshape package is good for this. 2. use the formula interface to lattice plotting functions: xyplot(y_var ~ x_var | panel_grouping_var, groups=color_grouping_var, data=your_dataframe, ...)
