You have unnecessarily asked for relation="free" for the x-axis (even
though they don't change across panels), and then tried to combine
them using combineLimits(), which doesn't know how to handle
categorical axes.
Change to using relation="free" for the y-axis only, and you should be fine.
bw <- bwplot(error ~ methods | attr * groups, data=df,
as.table=TRUE, notch=TRUE,
scales = list(y = list(alternating = c(1,1), tck=c(1,0),
relation = "free")))

No. (Well, you can provide your own axis() function to do it, in which
case you will need to allocate space too.)
