In crestr: A Probabilistic Approach to Reconstruct Past Climates Using Palaeoecological Datasets

Plots raster data in equal earth projection.

Description

Plots raster data in equal earth projection.

Usage

plot_map_eqearth(
  dat,
  ext = raster::extent(dat),
  zlim = range(raster::values(dat), na.rm = TRUE),
  col = viridis::viridis(20),
  brks.pos = c(0, 1),
  brks.lab = brks.pos,
  npoints = 15,
  nlines = 9,
  title = "",
  colour_scale = TRUE,
  top_layer = NA,
  top_layer.col = "ghostwhite",
  site_xy = NA,
  dim = NA
)

Arguments

dat	The raster data to plot.
ext	The extent to use to plot the data. (default is extent of dat)
zlim	The range of the values to plot. (default is estimated from dat)
col	The color gradient to use. (default is viridis)
brks.pos	The position where to draw tick marks on the legend
brks.lab	The labels to add where the tickmarks are draw (default is tickmarks position)
npoints	The number of points used to draw the polygons and lines along each dimension. (default is 15 for a smooth result)
nlines	The number of coordinate lines to add in the background (default is 9)
title	A description title (default is empty).
colour_scale	A boolean to add the colour scale to the plot (default TRUE).
top_layer	A raster to overlay on top of the map (e.g. a distribution).
top_layer.col	A colour for plotting top_layer (default 'ghostwhite').
site_xy	Coordinates of a location to add to the plot.
dim	The dimension of the plotting window in inches (default dev.size()).

Value

The set of coordinates ext projected in equal earth.
