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 289.0000000 4 recruits 4 44.2500000 36.0000000 54.7500000 5 richness 1 85.5000000 74.7500000 96.0000000 6 richness 4 90.2500000 82.0000000 100.2500000 7 shannon 1 3.9139870 3.7895134 4.0081557 8 shannon 4 3.9364410 3.8454223 3.9966735 9 simpson 1 0.9676981 0.9650888 0.9699434 10 simpson 4 0.9672897 0.9637745 0.9703296 11 survivors 1 0.0000000 0.0000000 0.0000000 12 survivors 4 252.5000000 232.0000000 273.0000000 library(lattice) library(grid) library(Hmisc) xYplot( Cbind(mean, Lower, Upper) ~ date | response, groups = water, data = sum.sap, type = "l", lty = c(1, 2), col = "black", scales = list(y = list(relation = "free")), ) When I run this code, ylim for each panel is 0 - 350. I want the ylimits of each panel to differ. Any help would be appreciated- thanks- tim Running R 2.6 on MAC OS 10.4 ______________________ C. E.
