R: Depth Graph

depth.graph {ddalpha} | R Documentation

## Depth Graph

### Description

Builds the data depth graphs for 2-dimensional data. The graph is built using `persp`.

### Usage

    depth.graph(data,
      depth_f = c("halfspace", "Mahalanobis", "projection", "simplicial",
                  "simplicialVolume", "spatial", "zonoid", "none"),
      apoint = NULL,
      main = depth_f,
      xlim = c(min(data[, 1]), max(data[, 1])),
      ylim = c(min(data[, 2]), max(data[, 2])),
      zlim = c(0, max(z)),
      xnum = 250,
      ynum = 250,
      theta=15, phi=60,
      bold = F,
      ...)

### Arguments

`data` | 2-dimensional numeric data frame or matrix
`depth_f` | the name of the depth function. The list of the supported depths and described in the topic `depth.`.
`apoint` | a 2-dimensional point which is shown in black color.
`main` | an overall title for the plot: see `title`
`xlim, ylim, zlim` | numeric vectors of length 2, giving the x, y and z coordinates ranges: see `plot.window`
`xnum, ynum` | number of points on each direction, x and y. Impacts the smoothness of the surface.
`theta, phi` | rotation angles
`bold` | draws bold points
`...` | additional parameters passed to `persp`

### See Also

    ## Not run:

    par(mfrow = c(2,3), mar = c(0,0,0,0), mai = c(0,0,0.2,0))
    data(hemophilia)
    depth.graph(hemophilia, "none", xnum = 100, ynum = 100)
    depth.graph(hemophilia, "Mahalanobis", xnum = 100, ynum = 100)
    depth.graph(hemophilia, "halfspace", xnum = 100, ynum = 100)
    depth.graph(hemophilia, "projection", xnum = 100, ynum = 100)
    depth.graph(hemophilia, "zonoid", xnum = 100, ynum = 100)
    depth.graph(hemophilia, "spatial", xnum = 100, ynum = 100)
