\title{
  Smooth a Signed or Vector-Valued Measure
}
\description{
  Apply kernel smoothing to a signed measure or vector-valued measure.
}
\usage{
 smooth.msr(X, ...)
}
\arguments{
  \item{X}{
    Object of class \code{"msr"} representing a
    signed measure or vector-valued measure.
  }
  \item{\dots}{
    Arguments passed to \code{\link{density.ppp}} controlling the
    smoothing bandwidth and the pixel resolution.
  }
}
\details{
  This function applies kernel smoothing to a signed measure or
  vector-valued measure \code{X}. The Gaussian kernel is used.

  The object \code{X} would typically have been created by
  \code{\link{residuals.ppm}} or \code{\link{msr}}.
}
\value{
  For signed measures, a pixel image (object of class \code{"im"}).
  For vector-valued measures, a list of pixel images; the list also
  belongs to the class \code{"listof"} so that it can be printed and plotted.
