nObsPoints | R Documentation |
This functions returns the number of observation points in an object of class
funData
, multiFunData
or irregFunData
.
nObsPoints(object)
object |
An object of class |
Depending on the class of object
, the function returns different
values:
If object
is of class funData
, the
function returns a vector of length dimSupp(object)
, giving the number
of observations in each dimension.
If object
is of class
multiFunData
, the function returns a list of the same length as
object
, where the j
-th entry is a vector, corresponding to the
observations point of object[[j]]
.
If object
is of class
irregFunData
, the function returns an array of length
nObs(object)
, where the j
-th entry corresponds to the number of
observations in the j
-th observed function.
The number of observation points in object
. See Details.
Do not confound with nObs
, which returns the
number of observations (i.e. the number of observed functions) in an object
of a functional data class.
