Sort a 'timeSeries' by time stamps
Description
Sort a "timeSeries"
object with respect to its time stamps.
Usage
## S4 method for signature 'timeSeries'
sort(x, decreasing = FALSE, ...)
Arguments
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. |
Details
Sorts a time series either in increasing or decreasing time
stamp order. Internally the function order
from R's
base package 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.
Value
a "timeSeries"
object
Examples
## 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)
