Which time steps fall within two extreme values
Description
Given two extreme character timestamps, return a logical vector of a length
equal to the number of time steps in the CFtime instance with values TRUE
for those time steps that fall between the two extreme values, FALSE
otherwise. This can be used to select slices from the time series in reading
or analysing data.
Usage
slab(x, extremes)
Arguments
x |
CFtime. The time series to operate on. |
extremes |
character. Vector of two timestamps that represent the extremes of the time period of interest. The timestamps must be in increasing order. The timestamps need not fall in the range of the time steps in the CFtime stance. |
Details
If bounds were set these will be preserved.
Value
A logical vector with a length equal to the number of time steps in
x with values TRUE for those time steps that fall between the two
extreme values, FALSE otherwise. The earlier timestamp is included, the
later timestamp is excluded. A specification of c("2022-01-01", "2023-01-01")
will thus include all time steps that fall in the year 2022.
Examples
cf <- CFtime("hours since 2023-01-01 00:00:00", "standard", 0:23)
slab(cf, c("2022-12-01", "2023-01-01 03:00"))
