Examples

## Not run: 
require(fda)
require(Rfssa)
data(Callcenter) # Read data
u=seq(0,1,length.out=240) # Define domain of functional data
d=12 # number of basis elements
basis=create.bspline.basis(rangeval = c(0,1),nbasis = d) # create basis object
smooth.calls=smooth.basis(u, matrix(nrow=240,ncol=365,Callcenter$calls), basis)
Y=fts(smooth.calls$fd) # create functional time series
plot(Y)
Yminus=Y[4:8]-Y[14:18] # subtract elements of the functional time series from each other
plot(Yminus)
Yminus2=Y-2 # add 2 to every term in the functional time series
plot(Yminus2)
