[R] Help with selecting data from irregular time series {its} objects
If I understood correctly in irregular time series (its) objects, values are indexed by time stamps in POSIX format. But if I try to select the value of my time series corresponding to specific time stamp in the following way: x - its object i <- as.POSIXct("2006-05-19 15:30:00") x[i,] or x[i] or x[i,1] I get the error message: subscript out of bounds. If I use integers: x[1,1] it is ok I get the first element of time series. Is there a way to select elements by their corresponding dates? [[alternative HTML version deleted]]
