\title{DTW kernel features}
\usage{
extractFDADTWKernel(
ref.method = "random",
n.refs = 0.05,
refs = NULL,
dtwwindow = 0.05
)
}
\arguments{
\item{ref.method}{(\code{character(1)})\cr
How should the reference curves be obtained?
Method \code{random} draws \code{n.refs} random reference curves, while \code{all} uses all curves as references.
In order to use user-provided reference curves, this parameter is set to \code{fixed}.}
\item{n.refs}{(\code{numeric(1)})\cr
Number of reference curves to be drawn (as a fraction of the number of observations in the training data).}
\item{refs}{(\code{matrix}|\code{integer(n)})\cr
Integer vector of training set row indices or a matrix of reference curves with the same length as
the functionals in the training data. Overwrites \code{ref.method} and \code{n.refs}.}
\item{dtwwindow}{(\code{numeric(1)})\cr
Size of the warping window size (as a proportion of query length).}
}
\value{
(\link{data.frame}).
}
\description{
The function extracts features from functional data based on the DTW distance with a reference dataframe.
