R: Plot Samples on World Map

sample.map {swfscMisc} | R Documentation

## 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)

### 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.

### Value

original `par` settings for `mar` and `oma`.

### 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)
