Dear R Gurus - Please help me to make a multiple-panel plot using xYplot in which the y-axis of each panel is dependent only on the data of that plot. Here is the dataset: response date mean Lower Upper 1 density 1 271.0000000 249.2500000 289.0000000 2 density 4 296.7500000 280.5000000 313.0000000 3 recruits 1 271.0000000 249.2500000
