SSplotMovementMap: Show movement rates on a map.

In r4ss: R Code for Stock Synthesis

Show movement rates on a map.

Description

Make a map with colored spatial cells and add arrows representing movement rates between cells.

Usage

SSplotMovementMap(
  replist = NULL,
  xlim,
  ylim,
  polygonlist,
  colvec,
  land = "grey",
  xytable = NULL,
  moveage = 5,
  moveseas = 1,
  lwdscale = 5,
  legend = TRUE,
  title = NULL,
  areanames = NULL,
  cex = 1
)

Arguments

replist	A list object created by SS_output().
xlim	range of longitude values in the map
ylim	range of latitude values in the map
polygonlist	a list of data frames, each with two columns representing the longitude and latitude values of the colored polygons. The order of elements in the list should match the numbering of areas in the SS model.
colvec	vector of colors for each polygon (if replist is provided)
land	color of landmasses in the map
xytable	data frame of latitude and longitude values which will be connected by the arrows representing movement rates. The order should match the order of areas in polygonlist and in the SS model. Not necessary if no arrows are shown on the map.
moveage	age for which movement rates will be represented
moveseas	season for which movement rates will be represented
lwdscale	scaling factor for arrows in the plot. The largest rate of movement shown will be scaled to have a line width equal to this value.
legend	add a legend to show the movement rate associated with the widest arrows
title	optional title to be added above map
areanames	optional vector of names to be shown on map at coordinates matching xytable values
cex	character expansion to apply to text shown by areanames (if used)

Note

Inspired by plots of MULTIFAN-CL movement patterns presented by Adam Langley
