Hi, I think this question is best explained using the following self-contained toy example:
## cut code here and paste to R window z <- cbind(rep(c("BIC", "hist"), each = 150), rep(rep(c(5, 10, 30), each = 50),2)) z <- as.data.frame(z) z <- cbind(z, runif(300)) names(z) <- c("Method", "sigma", "Error") library(lattice) bwplot(Error~Method | sigma, data = z, horiz = F, xlab = "Method", layout = c(3,1)) ## end code Now the question: I would like the panels to be in the order of sigma, i. e. 5, 10, 30 and not 10, 30 and 5 as is currently the case. Is this possible? Not to seek too much indulgence, but to ask anyway, I wonder if it is possible to have a Greek sigma = 5, a Greek sigma = 10 and a Greek sigma = 30. (Sort of what we would get using expression(sigma == 5), expression(sigma == 10), expression(sigma == 10) on "base" R figures). Please let me know if my question is not clear. Many thanks for any suggestions and help and best wishes!
