Hi,

I'm dealing with time series with 1 observaton for day

(data sampled daily). I will create a ts object using

that time series and the function ts().
In ts() help is written:

The value of argument 'frequency' is used when the
series is sampled an integral number of times in each
unit time interval. For example, one could use a value
of '7' for 'frequency' when the data are sampled
daily, and the natural time period is a week, or '12'
when the data are sampled monthly and the natural time
period

is a year. Values of '4' and '12' are assumed in

(e.g.) 'print' methods to imply a quarterly and

monthly series respectively.

But what value should assume start in ts function?

Here is a time series:

1/1 10 2/1 20 3/1 30 4/1 40 5/1 50 6/1 60

x<-c(10,20,30,40,50,60) ## observation

serie<-ts(dati, start=c(1,1),frequency=7) ##creating
ts object

serie ## printing ts output

Time Series:

Start = c(1, 1)

End = c(1, 6)

Frequency = 7

[1] 10 20 30 40 50 60

Could someone help me?

Thanks in advance.

Sincerely.

Vito Ricci
