Empty world map (Plate Carée)

Usage

emptymap(
  xlim = c(-180, 180),
  ylim = c(-90, 90),
  grat = c(30, 30),
  col = "#DDDDFE",
  grat.col = "#FFFFFF",
  lwd = 2,
  thick = lwd * 2,
  border = grat.col
)

Arguments

xlim: Standard xlim argument of par in degress longitude.
ylim: Standard ylim argument of par in degrees latitude.
grat: Graticule resolution. Use grat=NULL, if you don't want any.
col: Plot background, RGBA possible.
grat.col: Graticule color RGBA possible.
lwd: The baseline thickness of the lines.
thick: The 0-coordinate circles are highlighted with thicker lines, given here.
border: Border color of rectange on the outside of the plot.

Value

The function has no return value.
