Hi Frank, Thanks for the suggestion. using numericScale() does work for Dotplot, but there're still a few issues:
1. My factor names are Plot A, PF, MSF, and YSF, so numericScale turns that into 3, 2, 1, 4 and the x-axis is plotted 1, 2, 3, 4. Is there any way I can retain the same order on the graph? 2. I can't get the error bars displayed even after using method="bars", only the mean, lower and upper bounds of the data as points. This the line I used: Dotplot(cbind(mort, mort + stand, mort - stand) ~ numericScale(site) | type, data = mort, method="bands") Thanks for your help.
