Usage

fdata2fd(fdataobj, nbasis = 10, type = c("bspline", "fourier"))

Arguments

fdataobj: An object of class 'fdata'.
nbasis: Number of basis functions (default 10).
type: Type of basis: "bspline" (default) or "fourier".

Value

An object of class 'fd' from the fda package.

Examples

if (FALSE) { # \dontrun{
t <- seq(0, 1, length.out = 50)
X <- matrix(0, 20, 50)
for (i in 1:20) X[i, ] <- sin(2*pi*t) + rnorm(50, sd = 0.1)
fd <- fdata(X, argvals = t)
fd_obj <- fdata2fd(fd, nbasis = 10)
} # }
