[R] a question of alphabetical order

Hi all,

In Spanish vowels with accent like á, é, ... doesn't affect to the alphabetical order of vector of strings. I mean, a or á don't matter for establishing the alphabetical order.

Nevertheless, while working with R order, here is what I get.

Given a file transport.txt

medio#variable
avión#34
barco#33

bicicleta#3
ángulo#37
camión#54
coche#23
tren#67

> toPlot <-

read.csv("~/Desktop/Workplace/transport.txt",header=TRUE,sep="#")
> toPlot[order(toPlot$medio),]

      medio variable
1     avión       34
2     barco       33
3 bicicleta        3
5    camión       54
6     coche       23
7      tren       67
4    ángulo       37

I expect ángulo appears in the first place as n (in ángulo) goes before v (in avión) and á/a doesn't matter for alphabetical order.

But ángulo appears in the last position.

Here my environment:

Is it not possible to get this dataframe ordered correctly in Spanish? Other programs (Excel, for instance) do order correctly.

Thanks for your help,

Ricardo
