mapocc: mapocc

In macroecology/mapast: Paleogeography Combined with Spatial Paleobiodiversity

Description

Creates a RasterLayer, containing the number of occurrences per cell and a plot of the fossil occurrences by the taxonomic rank per cell (a proxy for the sampling effort).

Usage

mapocc(data, model = "SETON2012",
                   rank = "genus", map = NULL,
                   res = 1, save.as = NULL,
                   colland = "#66666660",
                   colsea = "#00509010", col.grid = mycols(100), do.plot = TRUE, ...)

Arguments

data	data.frame. Fossil occurrences data.
model	character. The model the map should be created with. "SETON2012" (default), "MULLER2016", "GOLONKA", "PALEOMAP" or "MATTHEWS2016".
rank	character. The taxonomic rank of interest. "species", "genus", "family", "order", "class" or "phylum". By default rank = "genus".
map	(list of) SpatialPolygonDataFrames. Containing map(s) which can be created by mapast::getmap(ma, model).
res	numeric. The spatial resolution. By default res = 1.
save.as	character. The format the plots should be saved. "tiff", "pdf", "jpeg" or "png".
colland	character. The color of the land masses. By default colland = "#66666660".
colsea	character. The color of the sea. By default colsea = "#00509010".
col.grid	character. The color of the raster. By default col.grid = mycols(100),
do.plot	logical. If a plot is created or not. By default do.plot = TRUE.
...	Graphical parameters. Any argument that can be passed to image.plot and to plot, such as main = "my own title" or main.col = "red".

Value

RasterLayer

# save the maps before so the function does not need to load them
maps <- getmap(ma = 2.5, model = "SETON2012", do.plot = FALSE)
mapocc(data = df_auto, model = "SETON2012", rank = "species", map = maps)

# save maps as pdf
