[R-es] como hacer un simple barchart horizontal ordenado por el valor ...

[eric]

Estimada comunidad, me resulta muy frustrante no poder hacer un simple 
barchart como yo quisiera (es la primera vez que intento hacer uno en 
todo caso :)). Gaste todo el dia buscando y no puedo darle las 
caracteristicas que necesito:

Tengo un simple data.frame que adjunto, con paises y los puntajes que 
obtuvieron en una prueba y quiero hacer un barchart con los puntajes en 
orden ascendente, con las barras horizontales y que muestre el nombre de 
los paises, aunque sea con la fuente pequeña. Uso el siguiente codigo y 
no resulta:

barchart(ave ~ CNT, data=math, horizontal=TRUE)

con eso consigo que sea horizontal, pero no se como hacer que las barras 
se ordenen de acuerdo al valor de "ave", lo que sospecho tiene que ver 
con "index.cond", pero no se como usarlo.

Tampoco puedo siquiera hacer que aparezca una leyenda con auto.key=TRUE

Alguna sugerencia ?

Adjunto los datos.

Muchas gracias.
