In carrollrm/fillmap: Create maps with SpatialPolygons objects

Create maps with SpatialPolygons objects

Description

This function offers several options for creating plots with SpatialPolygons objects. This can be a single plot or multiple plots. These multi-plots can have the same legend or individual legends. Additionally, the layout call within this function offers many options for improving the resulting figures.

Usage

fillmap(
  map,
  figtitle,
  y,
  n.col,
  bk = "e",
  cuts,
  legendtxt = "",
  leg.loc = "bottomright",
  leg.cex = 1.5,
  main.cex = 1.5,
  main.line = -2,
  leg.horiz = F,
  map.lty = 1
)

Arguments

map	The SpatialPolygon object.
figtitle	The title to be displayed on the map(s). Can be of length 1 or more.
y	The vector or matrix object to be mapped.
n.col	The number of legend levels.
bk	The break specifications defaults to "e" for equal. Other options are "c" to specify your own breaks and "q" for quantile breaks.
cuts	The cuts to be specified when bk="c".
legendtxt	The text to be displayed in the legend (must be NA (which removes the text altogether) or equal length n.col+1). Defaults to "" which creates text based on the cuts.
leg.loc	The loation for the legend defaults to "bottomright". Can also be given as a list of x,y coordinates
leg.cex	Specifies the font size in the legend. Defaults to 1.5.
main.cex	Specifies the font size for the title. Defaults to 1.5.
main.line	Specifies the line for the title of the plot to appear on. Defaults to -2.
leg.horiz	Indicates if the legend should be horizontal. Defaults to FALSE.
map.lty	Specifies the line type for the plot. Defaults to 1.
