## Create multiple scatterplots from ICA

### Description

Create multiple scatterplots from ICA

### Usage

    plotICA(ica, components = seq(10), groups = NULL, ...)

### Arguments

`ica` | Object resulting from `performICA`
`components` | Numeric: independent components to plot
`groups` | Matrix: groups to plot indicating the index of interest of the samples (use clinical or sample groups)
`...` | Arguments passed on to `pairsD3::pairsD3` group a optional vector specifying the group each observation belongs to. Used for tooltips and colouring the observations. subset an optional vector specifying a subset of observations to be used for plotting. Useful when you have a large number of observations, you can specify a random subset. labels the names of the variables (column names of `x` used by default). cex the magnification of the plotting symbol (default=3) width the width (and height) of the plot when viewed externally. col an optional (hex) colour for each of the levels in the group vector. big a logical parameter. Prevents inadvertent plotting of huge data sets. Default limit is 10 variables, to plot more than 10 set `big=TRUE`. theme a character parameter specifying whether the theme should be colour `colour` (default) or black and white `bw`. opacity numeric between 0 and 1. The opacity of the plotting symbols (default 0.9). tooltip an optional vector with the tool tip to be displayed when hovering over an observation. You can include basic html. leftmar space on the left margin topmar space on the bottom margin

### Value

Multiple scatterplots as a `pairsD3` object

### Examples

    data <- scale(USArrests)
    ica  <- fastICA::fastICA(data, n.comp=4)
    plotICA(ica)

    # Colour by groups
    groups <- NULL
    groups$sunny <- c("California", "Hawaii", "Florida")
    groups$ozEntrance <- c("Kansas")
    groups$novel <- c("New Mexico", "New York", "New Hampshire", "New Jersey")
    plotICA(ica, groups=groups)
