Hi,

you can address to a single ts in a multivariate ts object by namets[,index]. See this example:

*> dati
*

X Y

1 100 200

2 150 210

3 180 220

4 200 230

5 220 250

> serie<-ts(dati,start=1999)

*> serie
*

Time Series:

Start = 1999

End = 2003

Frequency = 1

X Y

1999 100 200

2000 150 210

2001 180 220

2002 200 230

2003 220 250

> serie[,1] ## first ts

Time Series:

Start = 1999

End = 2003

Frequency = 1

[1] 100 150 180 200 220

> serie[,2] ## second ts

Time Series:

Start = 1999

End = 2003

Frequency = 1

[1] 200 210 220 230 250

you wrote:

In a dataframe you call one of the variable (or the
column) connecting the

name of the column to the dataframe name by means of
the $ sign:

so z$energy is the column named energy in the
dataframe z.

I don't know how to do the same with a multi-variable
time-series. I tried

both z.energy, z$energy to no avail.

What's the right synthax?

Ciao

Vittorio

Top 10 reasons to become a Statistician

- Deviation is considered normal
- We feel complete and sufficient
- We are 'mean' lovers
- Statisticians do it discretely and continuously
- We are right 95% of the time
- We can legally comment on someone's posterior distribution
- We may not be normal, but we are transformable
- We never have to say we are certain
- We are honestly significantly different
- No one wants our jobs
