R help - Oct 2009 - Multiple time series and their names

Suppose I have multiple time series with names for each one, for example,

x <- ts(matrix(rnorm(30,0,1),10,3), names=c("Juan",
"Tuey", "Trey"),
frequency=4)

So now, as I start to explore these series, if I do everything at once, the
names
stay attached to the series.  For example,
plot(x) # gives a plot of the series with their names
acf(x)  # gives the ACFs & CCFs with names attached

But if I want to explore what's going on with Juan, from what I can gather, 
I have to do something like this
plot(x[,1])
(or acf(x[,1])... or similar things) but this doesn't keep the name Juan.

My question: Is there a way, without making a data frame [which seems to
destroy the
time series attributes(??) - this seems to be the only answer I can find on
Rhelp] 
that allows me to keep track of the names?  That way, for example, I don't
have to 
remember that the 18th series is Martha.  

x$Juan, x$Tuey, x$Trey, would be nice ... but that doesn't work.

Thanks in advance.

zoo objects can have one column with a heading and convert back
faithfully to ts:
> library(zoo)
> as.zoo(x)[, 1, drop = FALSE]
            Juan
1(1) -0.37415224
1(2) -0.30875111
1(3) -0.02617545
1(4) -0.45053564
2(1)  0.15173749
2(2)  1.38545761
2(3)  2.11594058
2(4) -0.84970010
3(1) -0.05944844
3(2)  1.27543030
> tsp(x)
[1] 1.00 3.25 4.00
> tsp(as.ts(as.zoo(x)))
[1] 1.00 3.25 4.00
