Sorting a 'timeSeries' by Time Stamps
Sorts a 'timeSeries' object with respect to its time stamps.
## S4 method for signature 'timeSeries' sort(x, decreasing = FALSE, ...)
x |
an uni- or multivariate |
decreasing |
a logical flag. Should we sort in increasing or decreasing order? By default FALSE. |
... |
optional arguments passed to other methods. |
Sorts a time series either in increasing or decreasing time
stamp order. Internally the function order from R's
base packahe is used. order generates a permutation
which rearranges the time stamps in ascending or descending
order.
To find out if the series is unsorted, the function
is.unsorted from R's base package can be called.
Returns a sorted 'timeSeries' object, which can be increasing or decreasing in time.
## Monthly Calendar Series - x <- daily2monthly(LPP2005REC[, 1:2])[3:14, ] ## Resample the Series with respect to the time stamps - resampled <- sample(x) resampled is.unsorted(resampled) ## Now sort the serie in decreasing time order - sorted <- sort(resampled, , decreasing = TRUE) sorted is.unsorted(sorted) ## Is the reverted series ordered? - reverted <- rev(sorted) reverted is.unsorted(reverted)
