I have a time series data in R. The data are in the following format:
datetime value
2012-04-18 14:22:09 342.82
2012-04-18 14:22:11 345.14
2012-04-18 14:22:12 341.68
2012-04-18 14:22:15 342.21
2012-04-18 14:22:16 342.36
The data are collected with frequency of 1 second, but some values are missing (for example the values of 2012-04-18 14:22:10, 2012-04-18 14:22:13, 2012-04-18 14:22:14). I just want to get these data added to the series by interpolation. How can I do this in R?
I tried this:
y <- zoo(x, frequency=1);
but I didn't get what I wanted.
Thanks!
