Hi everyone.

I have have a dataset with daily measurement from January 1st of 1966 up to
December 31th of 2011.

Here's the first part of the data:

Date	SLEV
1/1/1966	1.086
1/2/1966	1.079
1/3/1966	1.133
1/4/1966	1.261
1/5/1966	1.391
1/6/1966	1.571
1/7/1966	1.728
1/8/1966	1.823
1/9/1966	1.97
1/10/1966	1.804
1/11/1966	2.02
1/12/1966	2.017
1/13/1966	1.86
1/14/1966	1.96
1/15/1966	1.813
1/16/1966	1.773
1/17/1966	1.647
1/18/1966	1.634
1/19/1966	1.815
1/20/1966	1.928
1/21/1966	1.937
1/22/1966	2.187
1/23/1966	2.133
1/24/1966	2.162
1/25/1966	2.026
1/26/1966	2.055
1/27/1966	2.051
1/28/1966	1.998
1/29/1966	2.178
1/30/1966	1.709
1/31/1966	1.79
...
12/31/2011	0.599


I would like to perform some sort of time series analysis. To do so, I'm
trying to create a ts() object with my data. However, I'm not sure how ti
create it and what frequency to use. In the help file, they say to use
/*frequency = 7*/ for daily observation, but the result don't seems
coherent:

*/Series:
Start = c(1966, 1) 
End = c(4337, 5) 
Frequency = 7/ *

Anyone can help me? 

Thank is advance,
Phil
