data |
Input dataframe. This dataframe is the output of |
res |
the resolution of the RasterLayer object (in decimal degrees). See: |
col.int |
The colour of the mainland |
col.ocean |
The colour of the ocean |
col.eff |
Two or more colours. To generate the colour gradient used to show the number of occurrences per cell in map |
do.plot |
Logical; |

Others parameters. See |
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 the sampling effort (number of fossil records per cell). This RasterLayer object have the resolution controlled by the argument res
. The deflaut is res=1
