\title{Create a fluctuation plot.}
\usage{
  ggfluctuation(table, type = "size", floor = 0,
    ceiling = max(table$freq, na.rm = TRUE))
}
\arguments{
  \item{table}{a table of values, or a data frame with
  three columns, the last column being frequency}

  \item{type}{"size", or "colour" to create traditional
  heatmap}

  \item{floor}{don't display cells smaller than this value}

  \item{ceiling}{round cells to at most this value}

  \item{na.rm}{If \code{TRUE}, silently remove missing
  values.}
}
\description{
  A fluctutation diagram is a graphical representation of a
  contingency table.  This function only supports 2D
  contingency tables at present but extension to higher
  dimensions should be relatively straightforward.
}
\details{
  With the default size fluctuation diagram, area is
  proportional to the count (length of sides proportional
  to sqrt(count)).
