\title{Appends specified break to the data}
\usage{
appendbreak(data, brk, warp.model = warp.model, id = NULL, typ = "pred")
}
\arguments{
\item{data}{A data frame in the long long format}

\item{brk}{A vector of break ages}

\item{warp.model}{A time warping model}

\item{id}{The subject identifier}

\item{typ}{Label to signal that this is a newly added observation}
}
\value{
A long data frame with additional rows for the break ages
}
\description{
A custom function to insert rows in long data with new pseudo-observations
that are being done on the specified break ages. There should be a
column called \code{first} in \code{data} with logical data that codes whether
the current row is the first for subject \code{id}. Furthermore,
the function assumes that columns \code{age}, \code{occ},
\code{hgt.z}, \code{wgt.z} and
\code{bmi.z} are available. This function is used on the \code{tbc}
data in FIMD chapter 9. Check that out to see it in action.
