Hi, This issue comes from a thread of the same title, "a question of alphabetical order", initiated yesterday in [EMAIL PROTECTED] list. As it affects now only Mac environment, I follow Brian Ripley's advice and move it to this list.
It is now clear that ordering lists/variable values is a kind of nightmare whatever platform we use. As I (and possible many others!) need to get a right order, or an "as right as possible" order, for list of strings using non-ASCII character, namely áéíóú, ÁÉÍÓÚ and ñ,Ñ, we have been considering a number of options. Hans-Joerg Bibiko proposed a customized function to do the trick. Brian Ripley spoke about es_ES.ISO8859-15 doing almost the right thing for these characters. Here what I get working in a MacBook which environment I describe at the bottom of the message: http://mire.environmentalchange.net/~webmaster/images/toPlot.png Here the code: png(file="toPlot.png", pointsize = 14, width = 1000, height = 480, units = "px", bg="#eaedd5") Sys.setlocale(category = "LC_ALL", locale = "es_ES.ISO8859-15") toPlot <- data.frame(medio=c("avión", "barco", "bicicleta", "ángulo", "choco", "camión", "coche", "tren", "aleta", "luna", "llave"), variable=c(34, 33, 3, 37, 54, 23, 67, 30, 23, 56, 13)) toPlot<-toPlot[order(toPlot$medio),] Sys.setlocale(category = "LC_ALL", locale = "en_GB.UTF-8") barplot(toPlot$variable,names.arg=toPlot$medio) dev.off() As you see in the order of labels, accent is not ignored, and ch and ll are considered as single instances. These are not longer the case with Spanish alphabetical order. It changed in 1994. So, Hans's solution seems the only one available to the correct order. At least working with in the environment described below. In any case, please, 1. Are you aware of any new locale we could try to see if it is already updated? 2. If it doesn't exist, how/where must we go to propose/start creating such e locale?
