Extract and set slots from functional data objects
These functions can be used to extract and set the slots of
funData, irregFunData and multiFunData objects.

Objects of class funData or irregFunData have two slots,
argvals (for the x-values) and X (for the y-values for
each observation). Using the argvals (alias: getArgvals)
and X (alias: getX) methods for the classes
funData and irregFunData is equivalent to accessing the
slots directly via object@argvals and object@X.
Analogously, the argvals<- and X<- functions are
equivalent to setting object@argvals to value or
object@X to value, respectively. The new values must
hence have the same structure as the original ones. As an exception,
for an object of class funData the number of new X values may
differ from the current (e.g. when adding new observations). In this
case, the function throws a warning.
Objects of class multiFunData are lists of several
funData objects. The functions argvals and X for
multiFunData objects therefore return a list of the same length
as object, where each list element corresponds to the
argvals or X slot of the univariate element. The
argvals<- and X<- functions for multiFunData
objects must receive lists of the same length as object, where
each list element corresponds to the new argvals or new X
slot for the univariate elements.
See Details.
The functions getArgvals / getX and
setArgvals / setX from former package versions are
deprecated. use argvals and X instead.
### Univariate object <- funData(argvals = 1:5, X = rbind(1:5, 6:10)) object # get-methods argvals(object) X(object) # set-methods argvals(object) <- 0:4 object ## Not run: argvals(object) <- 1:4 # wrong length X(object) <- rbind(0:4, 5:9) ## Not run: X(object) <- rbind(0:4, 5:9, 10:14) # warning: now 3 observations (was 2 before) ## Not run: X(object) <- rbind(1:4, 5:8) # wrong length ### Univariate (irregular) irregObject <- irregFunData(argvals = list(1:5, 2:4), X = list(2:6, 3:5)) irregObject # get-methods argvals(irregObject) X(irregObject) # set-methods argvals(irregObject) <- list(0:4, 1:3) X(irregObject) <- list(12:16, 13:15) ### Multivariate multiObject <- multiFunData(object, funData(argvals = 1:3, X = rbind(3:5, 6:8))) multiObject # get-methods argvals(multiObject) X(multiObject) # set-methods (for special cases see univariate version) argvals(multiObject) <- list(5:1, 3:1) X(multiObject) <- list(rbind(5:1, 10:6), rbind(5:3, 8:6))
