## Graphical Display of Objects of Class "area"

### Description

`plot.area` allows a graphical display of objects of class `"area"`.

### Usage

    plot.area(x, which = levels(x[,1]),
              colpol = rep("green", nlevels(x[, 1])),
              colborder = rep("black", nlevels(x[, 1])),
              lwd = 2, add = FALSE, ...)

### Arguments

`x` | an object of class `"area"`
`which` | a vector of character indicating the polygons to be plotted
`colpol` | a vector of the color for filling the polygon. The default, `NA`, is to leave polygons unfilled
`colborder` | a vector of the color to draw the border. The default. Use `border = NA` to omit borders
`lwd` | the border width, a positive number
`add` | logical. if `TRUE`, the polygons are added to a previous plot
`...` | additional arguments to be passed to the generic function `plot`

### Examples

    ## Loading the relocations of wild boars
    ## monitored using radio-tracking
    data(puechabon)
    locs <-  puechabon$locs
    el <- getkasc(puechabon$kasc, "Elevation")

    ## Estimation of the MCP home ranges of the animals
    cp <- mcp(locs[,4:5], locs[,1])

    ## Use of plot.area to display the results
    plot(cp)

    ## different colors:
    color <- c("red", "blue", "green", "yellow")
    lev <- levels(cp[,1])
    image(el)
    plot(cp, colpol = color, add = TRUE)
    legend(697198, 3165529, legend = lev, fill = color)

    ## or:
    image(el)
    plot(cp, colborder = color, colpol = NA, add = TRUE)
    legend(697198, 3165529, legend = lev, fill = color)

    ## plots one animal
    image(el)
    plot(cp, which = "Brock", add = TRUE)
