+\title{Predict x from y values for calibration models}
+\description{
+  This function predicts x values from y values, as in classical calibration,
+  including a confindence interval.
+}
+\usage{
+  predictx(m,yobs,level=0.95)
+}
+\arguments{
+  \item{m}{
+    A calibration model of type \code{\link{calm}}.
+    }
+  \item{yobs}{ 
+    A vector of observed y values for one sample.
+    }
+  \item{level}{
+    The confidence level for the confidence interval to be reported.
+    }
+}
+\value{
+  A vector containing the estimate (\code{estimate}), its estimated standard
+  deviation (\code{sdxpred}), its estimated confidence (\code{confxpred}).
+} 
+\examples{
+  data(din32645)
+  m <- calm(din32645)
+  r <- predictx(m,3500,level=0.95)
+  cat("\nThe confidence interval is",r[["estimate"]],"+-",r[["confxpred"]],"\n")
