Hi, The solution to my problem is to use lattice:::calculateAxisComponents to calculate appropriate labels for the time axis in trellis plots. # For example, given x <- seq.POSIXt(strptime("2003/01/01", format = "%Y/%m/%d"), strptime("2003/10/01", format = "%Y/%m/%d"), by = "month") y <- rnorm(l...

..., data = dat, type = "b") However, the labelling for the x-axis is not what I want. (I see only one tick mark and one label ('Oct').) What is the recommended way to relabel the x-axis? Ideally, I want to see several months (3-6) labelled along the x-axis. Previously, I used 'calculateAxisComponents' to massage the labels manually but that function (which I realise was internal to lattice) is no longer available. I am on Windows XP, R 1.8.0.
