Hi ElliotThis works on Win 7 ver 2.15 useOuterStrips(combineLimits( xyplot(x + y ~ d | g, groups = h, data = dat, type = 'l', scales = list(y = list(relation = "free"), x = list( at =seq(from = as.Date("2011-01-01"), to = as.Date("2011-10-01"), by = "3 month"), labels = format(seq(from = as.Date("2011-01-01"), to = as.Date("2011-10-01"), by = "3 month"), "%b")) ), auto.key = TRUE) ))
This works because the x-limits don't require combining in this example; all panels have the same xlims. See below for a solution when the xlims are not equal.
amend the seq as required and the format if required see ?strptime for format HTH Duncan Duncan Mackay Department of Agronomy and Soil Science University of New England Armidale NSW 2351 Email: home: mac...@northnet.com.au At 02:28 26/06/2012, you wrote:I'm having some trouble using the latticeExtra 'combineLimits' function with a Date x-variable: require(lattice) set.seed(12345) dates<- seq(as.Date("2011-01-01"), as.Date("2011-12-31"), "days") dat<- data.frame(d = rep(dates, 4), g = factor(rep(rep(c(1,2), each = length(dates)), 2)), h = factor(rep(c("a", "b"), each = length(dates)*2)), x = rnorm(4 * length(dates)), y = rnorm(4 * length(dates))) plt1<- xyplot(x + y ~ d | g, groups = h, data = dat, type = 'l', scales = list(relation = "free"), auto.key = TRUE) plt1<- useOuterStrips(plt1) plt1<- combineLimits(plt1) The x-axis labels are right after the call to 'useOuterStrips' but they get converted to numeric after the call to 'combineLimits'. How do I keep them as date labels?
After combineLimits(plt1), the plt1 object will have an x.limits component that has the dates converted to numeric form. You can just modify that component with: plt1$x.limits <- lapply(plt1$x.limits, as.Date, origin = "1970-01-01") and then plot it. Peter Ehlers
