Hi: Look at as.table = TRUE and (perhaps) the skip = options in xyplot(). as.table = TRUE will put 1998 in the upper left corner and proceed row-wise.
Here's an example using the singer data: histogram( ~ height | voice.part, data = singer, nint = 17, endpoints = c(59.5, 76.5), layout = c(2,4), aspect = 1, xlab = "Height (inches)") histogram( ~ height | voice.part, data = singer, nint = 17, as.table = TRUE, endpoints = c(59.5, 76.5), layout = c(2,4), aspect = 1, xlab = "Height (inches)") The '2' voices are lower than the '1' voices, so the ordering is correct.
