[R] List of zoo multivariate series

[Research]

Hi,

I have a list which is basically a database of zoo multivariate objects:

      x.Date <- as.Date("2003-02-01") + c(1:100) - 1
      x <- zoo(rnorm(100), x.Date)
      z <- zoo(rnorm(100), x.Date)
      y <- zoo(rnorm(100), x.Date)
      k <- zoo(rnorm(100), x.Date)

     a<-merge(x,z)
     b<-merge(y,k)
     c<-merge(z,x,y)

     test<-list(a=a, b=b, c=c)

Can I access the elements of the list in a for/next do loop?

for example something like:

for (i in 1:3)
{
     x11()
     plot(test[i])
}

So far I can only recover the zoo objects as test$a, test$b etc. etc...

Thanks,
Costas
