Dear R Users, I am trying to do something quite simple: replace the elements of a zoo object. For some reason, the following code does not seem to work. How can I replace the value for the 14th of Dec of 2008 in the zoo object x below with 1 (it is currently NA).

I didn't notice the second question and was only answering your first question:
library(zoo)
x <- zoo(c(361.667, 389.875, NA, NA, 397.822, 395.667), as.Date("2008-12-11") + 0:5)
x[as.Date("2008-12-14")]
2008-12-14
NA
For the second question use window (window also works for the first question
as well):
window(x, as.Date("2008-12-14")) <- 1
x
2008-12-11 2008-12-12 2008-12-13 2008-12-14 2008-12-15 2008-12-16 361.667 389.875 NA 1.000 397.822 395.667 See ?window.zoo
