Map the fossil records
Description
The function opens a new window with a map showing the distribution of the fossil records as points. These points are coloured according to the number of occurrences per cell.
Usage
pbdb_map(
data,
col_int = "white",
pch = 19,
col_ocean = "black",
main = NULL,
col_point = c("light blue", "blue"),
do_plot = TRUE,
...
)
Arguments

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