Hi: To make a more legible ordering of the plots, it might be a good idea to make m$L1 an ordered factor rather than a character variable:
m$L1 <- ordered(m$L1, levels = paste('dataset', 1:15, sep = '')) # Lattice bwplot(value ~ x | L1, data = m, as.table = TRUE) # ggplot2 ggplot(m)+ geom_boxplot(mapping=aes(x, value))+ facet_wrap(~L1) Nice example!
