## Ploting PCA in a 3D space

### Description

Methdo to draw a plot for samples using three PC contained in an ExposomePCA

### Usage

    plot3PCA(
      object,
      cmpX,
      cmpY,
      cmpZ,
      phenotype,
      main,
      angle = 35,
      pch = 16,
      legend = TRUE,
      plines = TRUE
    )

### Arguments

`object` | An onbject of class ExposomePCA
`cmpX` | Component to be placed at X axis
`cmpY` | Component to be placed at Y axis
`cmpZ` | Component to be placed at Z axis
`phenotype` | Used to color samples by phentoype
`main` | Title for the plot
`angle` | (default `35`) angle between x and y axis.
`pch` | (default `16`) plotting "character", i.e. symbol to use.
`legend` | (default `TRUE`) If `TRUE` shows the legend.
`plines` | (default `TRUE`) If `TRUE` it draws the lines from each dot to the base plane.

### Value

A `list` with different graphics option from `scatterplot3d`.
