pbdb_map_richness (data, rank="species", do.plot=TRUE, res=5,
col.int="white", col.ocean="black",
col.rich=c("light blue","blue"),...)

`data`	Input dataframe. This dataframe is the output of `pbdb_occurrences` function using the argument: `show = c("phylo", "coords", "ident")`. See too: Details and Examples
`rank`	To set which taxon rank you are interested for calculate richness. The options are: "species", "genus", "family", "order", "class" or "phylum")
`do.plot`	Logical; `TRUE` the function returns a RasterLayer and a plot.
`res`	The resolution of the RasterLayer object (in decimal degrees). See: `raster`
`col.int`	The colour of the mainland
`col.ocean`	The colour of the ocean
`col.rich`	Two or more colours. To generate the colour gradient used to show the richness per cell in map
`...`	Others parameters. See `par` and `map`

CAUTION! The argument show = "coords" in pbdb_occurrences function is required. We recommend the use of a cairo device (X11) for better visualization of the graphs. See Examples

A RasterLayer object and a plot with richness of species, genera, families, etc. per cell. This RasterLayer object have the resolution controlled by the argument res. The default is res=1.
