## Visualisation of raw data for a smoothing-splines mixed-effects model

### Description

A visualisation of the raw data used to fit the smoothing-splines mixed-effects model is obtained. This is presented as a trellis plot where each panel shows the observations for one of the subjects as a scatter plot (with optional lines connecting the observations if `showRawLines` is `TRUE`). If `showModelFits` is `TRUE`, then these observations are overlaid with the fitted individual curve for that subject.

### Usage

    plotSmeRaw(x,xlab="Time",ylab="Y",mainTitle="",showModelFits=TRUE,showRawLines=FALSE,...)

### Arguments

`x` | an object inheriting from class `sme`, representing a fitted smoothing-splines mixed-effects model
`xlab` | the label for the x-axis, defaulting to `"Time"`
`ylab` | the label for the y-axis, defaulting to `"Y"`
`mainTitle` | the main title for the plot, defaulting to none
`showModelFits` | if `TRUE`, the fitted individual curve for each subject will be overlaid on their observations in their panel
`showRawLines` | if `TRUE`, the raw observations will be connected by lines
`...` | additional arguments passed through to `xyplot`

### Value

A trellis plot as described above.
