R help - Jun 2008 - Creating zoo object on monthly time series

Hi all,

I have following monthly time series :
> head(data1)
      V1 V2      V3
1 Nov-80 NA 1007.44
2 Dec-80 NA  982.05
3 Jan-81 NA  994.25
4 Feb-81 NA  996.31
5 Mar-81 NA  939.91
6 Apr-81 NA  923.32

Now I want to convert it to a 'zoo' object. I wrote following syntax :

ss = zoo(data1[,3], as.Date(data1[,1], format="%m/%y"))

However I got following :
> head(ss)
   <NA>    <NA>    <NA>    <NA>    <NA>   
<NA>
1007.44  982.05  994.25  996.31  939.91  923.32 


Can anyone please tell me what will be the correct syntax?

Thanks

If the suggestion below does not work then try
dput(head(data1)) to display it in an unambiguous form that is
readily re-input into R.

See ?strptime and try "%b-%y"
