+\title{
+ Function to calculate maximum time weighted average concentrations from kinetic models fitted with mkinfit
+}
+\description{
+This function calculates maximum moving window time weighted average concentrations
+(TWAs) for kinetic models fitted with \code{\link{mkinfit}}. Currently, only
+calculations for the parent are implemented for the SFO, FOMC and DFOP models,
+using the analytical formulas given in the PEC soil section of the FOCUS
+guidance.}
+\usage{
+ twa(fit, windows)
+}
+\arguments{
+ \item{fit}{
+ An object of class \code{\link{mkinfit}}.
+ }
+ \item{windows}{
+ The width of the time windows for which the TWAs should be calculated.
+ }
+}
+\value{
+ A numeric vector, named using the \code{windows} argument.
+}
+\examples{
+ fit <- mkinfit("FOMC", FOCUS_2006_C, quiet = TRUE)
