## Plotting 3D maps in correspondence analysis

### Description

Graphical display of correspondence analysis in three dimensions

### Usage

    ## S3 method for class 'ca'
    plot3d(x, dim = c(1, 2, 3), map = "symmetric", what = c("all", "all"),
                 contrib = c("none", "none"), col = c("#6666FF","#FF6666"),
                 labcol = c("#0000FF", "#FF0000"), pch = c(16, 1, 18, 9),
                 labels = c(2, 2), sf = 0.00001, arrows  = c(FALSE, FALSE),
                 axiscol = "#333333", axislcol = "#333333",
    			 laboffset = list(x = 0, y = 0.075, z = 0.05), ...)

### Arguments

`x` | Simple correspondence analysis object returned by ca
`dim` | Numerical vector of length 2 indicating the dimensions to plot
`map` | Character string specifying the map type. Allowed options include `"symmetric"` (default) `"rowprincipal"` `"colprincipal"` `"symbiplot"` `"rowgab"` `"colgab"` `"rowgreen"` `"colgreen"`
`what` | Vector of two character strings specifying the contents of the plot. First entry sets the rows and the second entry the columns. Allowed values are `"none"` (no points are displayed) `"active"` (only active points are displayed, default) `"supplementary"` (only supplementary points are displayed) `"all"` (all available points) The status (active or supplementary) is set in `ca`.
`contrib` | Vector of two character strings specifying if contributions (relative or absolute) should be indicated by different colour intensities. Available options are `"none"` (contributions are not indicated in the plot). `"absolute"` (absolute contributions are indicated by colour intensities). `"relative"` (relative conrributions are indicated by colour intensities). If set to `"absolute"` or `"relative"`, points with zero contribution are displayed in white. The higher the contribution of a point, the closer the corresponding colour to the one specified by the `col` option.
`col` | Vector of length 2 specifying the colours of row and column profiles. Colours can be entered in hexadecimal (e.g. `"\#FF0000"`), rgb (e.g. `rgb(1,0,0)`) values or by R-name (e.g. `"red"`).
`labcol` | Vector of length 2 specifying the colours of row and column labels.
`pch` | Vector of length 2 giving the type of points to be used for rows and columns.
`labels` | Vector of length two specifying if the plot should contain symbols only (`0`), labels only (`1`) or both symbols and labels (`2`). Setting `labels` to `2` results in the symbols being plotted at the coordinates and the labels with an offset.
`sf` | A scaling factor for the volume of the 3d primitives.
`arrows` | Vector of two logicals specifying if the plot should contain points (FALSE, default) or arrows (TRUE). First value sets the rows and the second value sets the columns.
`axiscol` | Colour of the axis line.
`axislcol` | Colour of the axis labels.
`laboffset` | List with 3 slots specifying the label offset in x, y, and z direction.
`...` | Further arguments passed to the rgl functions.
