The function fdata.cen centres the curves by subtracting the functional mean.

Usage

fdata.cen(fdataobj, meanX = func.mean(fdataobj))

Arguments

fdataobj

fdata class object.

meanX

The functional mean subtracted in the fdatobj.

Value

Return:

Xcen

The centered fdata.

meanX

Functional mean substracted.
