Thank you for your suggestion. Unfortunately it does not appear to matter if the data is subsetted before the xyplot command or within it. The problem remains.
I was able to remove method 4 entirely from the key by using your suggestion to subset the dataset “common,” and then creating a new variable to assign labels for just this subset “common.without.Method4$method.not4.f” The resulting code was: xyplot(MeanBxg ~ PercentVarExplained | bdg.f * bdx.f, data=common.without.Method4, groups=method.not4.f, type="l", auto.key=T) This however leads to lack of continuity between plots, as when I exclude methods 4 and 6 in my second plot, using the same approach, the color that had corresponds to methods 7, 8 and 9 in plot one is automatically changed in plot two. The subsetting may work, so long as I can dictate line color and symbol type in each plot.
