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?
