tsp {stats} | R Documentation |
tsp
returns the tsp
attribute (or NULL
).
It is included for compatibility with S version 2. tsp<-
sets the tsp
attribute. hasTsp
ensures x
has a
tsp
attribute, by adding one if needed.
tsp(x) tsp(x) <- value hasTsp(x)
x |
a vector or matrix or univariate or multivariate time-series. |
value |
a numeric vector of length 3 or NULL . |
The tsp
attribute was previously described here as
c(start(x), end(x), frequency(x))
, but this is incorrect.
It gives the start time in time units, the end time and
the frequency.
Assignments are checked for consistency.
Assigning NULL
which removes the tsp
attribute
and any "ts"
class of x
.
