sample.map: Plot Samples on World Map

Description

Plot a set of samples on a world map.

Usage

sample.map(
  lat,
  lon,
  lat.range = NULL,
  lon.range = NULL,
  main = NULL,
  pch = 19,
  pt.cex = 1,
  col = "black",
  bg = col,
  n = 5,
  lon.n = n,
  lat.n = n
)

Value

original par settings for mar and oma.

Arguments

lon, lat

vectors giving the longitude and latitude of points to plot.

lon.range, lat.range

vectors giving the minimum and maximum longitude and latitude of the map. If the first value in lon.range is greater than the second value, then a Pacific-centric map (world2Hires) is used and continents will not be filled in.

main

main title for the plot.

pch

point symbol to use.

pt.cex

point size to use.

col

point color.

bg

background color of point.

n, lon.n, lat.n

the number of tick marks desired. Can be specified separately for longitude (lon.n) or latitude (lat.n). See pretty for more details.

Examples

# Some random points around San Diego, CA
lat <- runif(30, 32.5, 33.3)
lon <- runif(30, -118.3, -117.5)
lat.range <- c(32.4, 33.6)
lon.range <- c(-118.6, -117)
sample.map(lat, lon, lat.range, lon.range)

# Some random points in the Pacific
lat <- runif(30, 20, 50)
lon <- c(runif(15, 150, 180), runif(15, -180, -120))
lat.range <- c(10, 75)
lon.range <- c(110, -110)
sample.map(lat, lon, lat.range, lon.range)
