## Fluctuation plot

### Description

Create a fluctuation plot.

### Usage

    ggfluctuation(table, type="size", floor=0, ceiling=max(table$freq, na.rm=TRUE))

### Arguments

`table` | a table of values, or a data frame with three columns, the last column being frequency
`type` | size, or colour to create traditional heatmap
`floor` | don't display cells smaller than this value
`ceiling` |

### Details

A fluctutation diagram is a graphical representation of a contingency table. This fuction currently only supports 2D contingency tabless but extension to more should be relatively straightforward.

With the default size fluctuation diagram, area is proportional to the count (length of sides proportional to sqrt(count))
