+\title{
+Evaluate parent kinetics using the NAFTA guidance
+}
+\usage{
+nafta(ds, title = NA, quiet = FALSE)
+}
+\description{
+ The function fits the SFO, IORE and DFOP models using
+ \code{\link{mmkin}} and returns an object of class
+ \code{nafta} that has methods for printing and plotting.
+}
+\arguments{
+ \item{ds}{
+ A dataframe that must contain one variable called "time" with the time
+ values specified by the \code{time} argument, one column called "name" with
+ the grouping of the observed values, and finally one column of observed
+ values called "value".
+ }
+ \item{title}{ Optional title of the dataset }
+ \item{quiet}{ Should the evaluation text be shown? }
+}
+\value{
+ An list of class \code{nafta}. The list element named "mmkin" is the
+ \code{\link{mmkin}} object containing the fits of the three models.
+ The list element named "title" contains the title of the dataset used.
+ The list element "data" contains the dataset used in the fits.
