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
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.
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"))

See ?strptime and try "%b-%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
