R: Global Plot

GlobeView {GEOmap} | R Documentation

## Global Plot

### Description

Plot global view of the earth

### Usage

    GlobeView(phicen, lamcen, worldmap, MAXR, SEL = 1,
    circol = rgb(1, 0.8, 0.8), innercol = "white", linecol = rgb(0, 0, 0),
     mapcol = rgb(0, 0, 0), backcol = "white", add=FALSE)

### Arguments

`phicen` | Latitude
`lamcen` | Longitude
`worldmap` | Map List
`MAXR` | Maximum radius (degrees)
`SEL` | Selection index from map
`circol` | color for concentric circles
`innercol` | inner color
`linecol` | line color, NA=do not plot
`mapcol` | map fill color, NA=do not fill polygon
`backcol` | background color
`add` | logical, FALSE means start a new plot

### Details

Creates a plot of view of the globe from a point in space using an Equal-Area projection. Uses the lamaz.eqarea routine for projection. (Lambert-Azimuthal Equal Area). Using NA for linecol or mapcol means do not plot lines or fill polygons respectively.

### Value

`Perimeter` | x,y points around the perimeter of the plot

    lamcen  = 335.7092+20
    MAXR    = 100

    carolinablue = rgb(83/255, 157/255, 194/255)

    SEL=which( coastmap$STROKES$code=="C")
    SEL = c(SEL, which(coastmap$STROKES$nam=="GreatBritain"),
    which(coastmap$STROKES$nam=="Japan"), which(coastmap$STROKES$nam=="Ireland"))

    PER = GlobeView(phicen, lamcen, SEL=SEL, coastmap, MAXR,
    linecol=rgb(.2, .2, .2), mapcol=rgb(.8, .8, .8),
    innercol=carolinablue , circol=carolinablue ,    backcol="white")
