\title{Join ratetables}
\usage{
joinrate(tables, dim.name = "country", merge = FALSE)
}
\arguments{
\item{tables}{a list of ratetables. If names are given, they are included as
\code{dimnames}.}
\item{dim.name}{the name of the added dimension.}
\item{merge}{if FALSE (default) only the intersect of all years/ages is taken.
If TRUE all possible years/ages are included (NOTE: in this case hazards are extrapolated
from earlier or later years/ages). This option only works for ratetables with dimensions}
}
\value{
An object of class \code{ratetable}.
}
\description{
The function joins two or more objects organized as \code{ratetable} by
adding a new dimension.
}
\details{
This function joins two or more \code{ratetable} objects by adding a new
dimension. The cutpoints of all the rate tables are compared; if merge=FALSE
(default) only the common intervals are kept, otherwise if merge=TRUE all
intervals are added (and hazards are extrapolated).
If the intervals defined by the cutpoints are not of
the same length, a warning message is displayed. Each rate table must have
the same dimensions.
}
\examples{
#newpop <- joinrate(list(Arizona=survexp.az,Florida=survexp.fl,
# Minnesota=survexp.mn),dim.name="state")
