In galuardi/SatTagSim: Simulation from Electronic Tags

Description

Get starting points Get starting points for simulations based on distribution of observed locations for a given month.

Usage

get.start.pts(
  dat,
  n = 100,
  months = 1:12,
  mask = rmask,
  posnames = c("coords.x1", "coords.x2")
)

Arguments

dat	input data. see data(nsdata)
n	number of starting points
posnames	names of the longitude and latitude columns in the data frame

Details

The number of starting points is the number of tracks desired for simulation in a given month

Value

a list of starting points

Examples

library(fields)
data(nsfish)
spts = get.start.pts(nsfish)
world(xlim = c(-100, 0), ylim = c(20, 50))
lapply(spts, points, pch = 19, cex = .4)
