R: Coordinate Reference System strings for some oceans

oceCRS {oce} | R Documentation

## Coordinate Reference System strings for some oceans

### Description

Create a coordinate reference string (CRS), suitable for use as a `projection` argument to `mapPlot()` or `plot,coastline-method()`.

### Usage

    oceCRS(region)

### Arguments

`region` | character string indicating the region. This must be in the following list (or a string that matches to just one entry, with `pmatch()`): `"North Atlantic"`, `"South Atlantic"`, `"Atlantic"`, `"North Pacific"`, `"South Pacific"`, `"Pacific"`, `"Arctic"`, and `"Antarctic"`.

### Value

string contain a CRS, which can be used as `projection` in `mapPlot()`.

### Caution

This is a preliminary version of this function, with the results being very likely to change through the autumn of 2016, guided by real-world usage.

### Examples

    library(oce)
    data(coastlineWorld)
    par(mar=c(2, 2, 1, 1))
    plot(coastlineWorld, proj=oceCRS("Atlantic"), span=12000)
    plot(coastlineWorld, proj=oceCRS("North Atlantic"), span=8000)
    plot(coastlineWorld, proj=oceCRS("South Atlantic"), span=8000)
    plot(coastlineWorld, proj=oceCRS("Arctic"), span=4000)
    plot(coastlineWorld, proj=oceCRS("Antarctic"), span=10000)
    # Avoid ugly horizontal lines, an artifact of longitude shifting.
    # Note: we cannot fill the land once we shift, either.
    pacific <- coastlineCut(coastlineWorld, -180)
    plot(pacific, proj=oceCRS("Pacific"), span=15000, col=NULL)
    plot(pacific, proj=oceCRS("North Pacific"), span=12000, col=NULL)
    plot(pacific, proj=oceCRS("South Pacific"), span=12000, col=NULL)
