time {timeSeries} | R Documentation |
Functions and methods extracting and modifying positions
of 'timeSeries' objects.
The functions and methods for the Generation of 'timeSeries' Objects are:
time.timeSeries | Extracts time positions from a 'timeSeries', |
time<-.timeSeries | Assign time positions to a 'timeSeries', |
sample.timeSeries | Resamples a 'timeSeries' object in time, |
sort.timeSeries | Sorts reverts a 'timeSeries' object in time, |
rev.timeSeries | Reverts a 'timeSeries' object in time, |
start.timeSeries | Extracts start date of a 'timeSeries' object, |
end.timeSeries | Extracts end date of a 'timeSeries' object. |

timeSeries
read.timeSeries
as.timeSeries
return a S4 object of class timeSeries
.
seriesData
seriesPositions
extract the @.Data
and @position
slots from a
timeSeries
object. Thus, seriesData
returns an
object of class matrix
, and seriesPositions
returns an object of class timeDate
.
is.timeSeries
returns TRUE
or FALSE
depending on whether its
argument is of timeSeries
type or not.
aggregateSeries
applySeries
cutSeries
mergeSeries
returnSeries
revSeries
return a S4 object of class timeSeries
.
end, start
return a S4 object of class timedate
. These are the
start and end dates of a timeSeries
object.
as.vector
as.matrix
as.data.frame
these are methods which convert a S4 object of class timeSeries
either to a vector, a matrix or to a data frame.
plot
lines
points
print
plot and print methods for an object of class timeSeries
.
Note that the plot function requires the packages its
and
Hmisc
.
## Create Dummy timeSeries: X = timeSeries(matrix(rnorm(24), 12), timeCalendar()) ## Return Series Positions - time(X)
