[R] Need help on index for time series object

[Megh Dal]

Dear all,

Please forgive me if there is a duplicate post; my previous mail perhaps didnt reach the list.......

Let say I have following time series

library(zoo)
> dat1 <- zooreg(rnorm(10), start=as.Date("2010-01-01"), frequency=1)
> dat1[c(3, 7,8)] = NA
> dat1
2010-01-01  2010-01-02  2010-01-03  2010-01-04  2010-01-05  2010-01-06  2010-01-07  2010-01-08  2010-01-09  2010-01-10
0.31244288 -2.49383257          NA  0.38975582 -1.23040380 -0.09697926          NA          NA -0.63171455  0.15867246

Now I want to get the Indies for the non-NA elements of dat1. Means I want to get a vector like: "1,2,4,5,6,9.10"

Having a time series vector like dat1, is there any straightforward approach to get that?

Thanks and regards,
