# 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

1 | ```
plotSmeRaw(x,xlab="Time",ylab="Y",mainTitle="",showModelFits=TRUE,showRawLines=FALSE)
``` |

### Arguments

`x` |
an object inheriting from class |

`xlab` |
the label for the x-axis, defaulting to |

`ylab` |
the label for the y-axis, defaulting to |

`mainTitle` |
the main title for the plot, defaulting to none |

`showModelFits` |
if |

`showRawLines` |
if |

### Value

A trellis plot as described above.
