[R] plot.ts

[kjetil@acelerate.com]

I have problems getting sensible series name plotted
with the ts.plot function. It doesn't seem to 
use either ylab= or xy.labels= arguments. 
I ended up using

plot({arg <- ts.union(gasolina.eq, PIBmensPred, PIBgrowthmens) ;
       colnames(arg) <- c("Gaso" ,"PIB", "PIBgrowth");arg },
   main="Gasolina eq. con crecimiento Economico", 
   xlab="Tiempo")

There must be a more natural way?
