\title{
Synthetic Classification Problem
}
\description{
The \code{synth.tr} data frame has 250 rows and 3 columns.
The \code{synth.te} data frame has 100 rows and 3 columns.
It is intended that \code{synth.tr} be used from training and
\code{synth.te} for testing.
}
\usage{
synth.tr
synth.te
}
\format{
These data frames contains the following columns:
\describe{
\item{\code{xs}}{
x-coordinate
}
\item{\code{ys}}{
y-coordinate
}
\item{\code{yc}}{
class, coded as 0 or 1.
