Dear expeRts,
How can I get plotmath-labels in the bwplot below?
As you can see, I couldn't manage to pass the expressions through
the dimnames
argument.
It would have been helpful, and may still be necessary, for you to
explain more fully what you were attempting to do. See if this effort
was informative.

## data
dim <- c(100, 6, 2, 3)
# did not find the dimnames object useful

data <- rexp(prod(dim))
arr <- array(data=data, dim=dim, dimnames=dimnames)
z <- abs(sweep(arr, 3, 1))
df <- as.data.frame.table(z, responseName="error")
## box plot
bwplot(error ~ methods | attr * groups, data=df,
as.table=TRUE, outer=FALSE, strip=TRUE, notch=TRUE,
scales=list(alternating=c(1,1), tck=c(1,0)))

) )
