\title{
  Access the metadata from an \code{mzR} object.
}

\usage{
runInfo(object)
analyzer(object)
detector(object)
instrumentInfo(object)
ionisation(object)
manufacturer(object)
model(object)
}
\arguments{
  \item{object}{An instantiated \code{mzR} object.}
}

\description{
  Accessors to the analytical setup metadata of a run.
  \code{runInfo} will show a summary of the experiment as a named list,
  including \code{scanCount}, \code{lowMZ}, \code{highMZ}, \code{startMZ},
  \code{endMZ}, \code{dStartTime} and \code{dEndTime}.
  The \code{instrumentInfo} method returns a named \code{list} including
  instrument manufacturer, model, ionisation technique, analyzer and
  detector. These individual pieces of information can also be directly
  accessed by the specific methods.

  See for example \code{\link{peaks}} to access the data for the spectra
  in a \code{"\linkS4class{mzR}"} class.
