## 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)
