Added new argument \code{labels} to designAnatomy, which has option \code{sources} that will result in sources indicating whether they represent interactions and/or nested effects. Added argument \code{marginality} that allows a list of marginality matrices to be supplied. Added the argument \code{check.marginality} allows one to decide if the supplied and calculated marginality matrices are the same. 
    \item Added argument \code{labelswap} to summary.pcanon so that can swap between terms and sources in the output.
    \item Added new method marginality.pcannon to extract the list of marginality matrices corresponding to the \code{formulae} in the call to designAnatomy. Added the argument \code{labelswap} to the summary.pcanon method so that either terms or sources can be output.

  \itemize{
    \item Add arguments rchtdiv and cchtdiv to design.plot so that can size row and column labels independetly of the cell labels. 
  }
}
\section{Changes in dae version 2.7-7 (2015-11-15)}{
  \itemize{
    \item Improved the documentation of efficiency criteria in a number of functions. 
  }
}
\section{Changes in dae version 2.7-6 (2015-11-02)}{
  \itemize{
    \item Allow a single formula to be specified in formula of projs.canon.
    \item Improved proj2.combine to equate Qconf to Q1 when all of Q1 is confounded by Q2. 
  }
}
\section{Changes in dae version 2.7-5 (2015-10-29)}{
  \itemize{
    \item Fix bug in mat.banded in which the elements were being placed starting with the first subdiagonal instead of the diagonal. 
  }
}
\section{Changes in dae version 2.7-4 (2015-10-01)}{
  \itemize{
    \item Add arrgument \code{ggplotFuncs} to interaction.ABC.plot to allow \code{ggplot} functions to be used to 
    modify the plot. 
    \item Add detect.diff to allow the calculation of the detectable difference for given replication, power, delta and alpha.
  }
}
\section{Changes in dae version 2.7-3 (2015-08-23)}{
  \itemize{
    \item Change option \code{differencingfirst} to \code{differencing} in projs.structure and projs.canon. 
          Code modified so that differencing only orthogonalizes by subtracting from a projector those 
          projectors whose factors are a subset of its factors. 
    \item Added new criteria \code{dforth} to efficiency.criteria.
    \item Added \code{order} to the default setting of \code{which.criteria} in all functions that have this argument.
    \item NEWS added.
  }
}
\section{Changes in dae version 2.7-2 (2015-06-24)}{
  \itemize{
    \item minor reprogramming.
    \item documentation of deprecated functions added.
    \item NEWS added.
  }
}
\section{Changes in dae Version 2.7-1 (2015-05-26)}{
  \itemize{
    \item An except argument added to fac.layout so that nominated unrandomized factors are not
          permuted.
  }
}
\section{Changes in dae Version 2.7-0 (2015-04-29)}{
  \itemize{
    \item Added functions to perform an eigenalysis of the projection matrices for an experimental  
          design to produce the decomposition or skeleton-anova table. These functions include 
          projs.combine.p2canon, projs.structure, projs.2canon, projs.canon, summary.p2canon, 
          summary.pcanon, print.summary.p2canon, print.summary.pcanon. The top-level functions 
          are those with the suffix 'pcanon'.
    \item This version uploaded to CRAN.
