Hi there, I would like to omit some observations of a zoo vector
corresponding with some defined dates. So I wrote following codes:
> set.seed(1)
> dates <- seq(as.Date("2011-01-01"), as.Date("2011-01-31"), by="1
day")[-c(7,8,9,20,21,22)]
> mySeries <- zoo(rnorm(25), dates)
> mySeries
2011-01-01 2011-01-02 2011-01-03 2011-01-04 2011-01-05 2011-01-06
2011-01-10 2011-01-11 2011-01-12 2011-01-13 2011-01-14 2011-01-15

Error in `-.Date`(toOmit) : unary - is not defined for Date objects
Can somebody point me how to rectify that error?
Thanks and regards,
