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?
