\title{ OneR algorithm }
\description{
The algorithms find weights of discrete attributes basing on very simple association rules involving only one attribute in condition part.
}
\usage{
oneR(formula, data)
}
\arguments{
\item{formula}{ a symbolic description of a model }
\item{data}{ data to process }
}
\details{
The algorithm uses OneR classifier to find out the attributes' weights. For each attribute it creates a simple rule based only on that attribute and then calculates its error rate.
}
\value{
a data.frame containing the worth of attributes in the first column and their names as row names
}
