Plots a rank *vs* relative abundance diagram.

## Usage

```
plot_rank(object, ...)
# S4 method for matrix
plot_rank(object, log = NULL, facet = FALSE)
```

## Arguments

- object
An abundance matrix to be plotted.

- ...
Further arguments to be passed to internal methods.

- log
A `character`

string which contains "`x`

" if the x axis is to be
logarithmic, "`y`

" if the y axis is to be logarithmic and "`xy`

" or "`yx`

"
if both axes are to be logarithmic (base 10).

- facet
A `logical`

scalar: should a matrix of panels defined by
case/sample be drawn?

## Examples

```
## Abundance matrix
## Coerce datasets to a count matrix (data from Desachy 2004)
data("compiegne", package = "folio")
counts <- as_count(compiegne)
## Plot rank vs abundance
plot_rank(counts)
plot_rank(counts, facet = TRUE)
```
