Draw a X Y scatter plot with associated X and Y histograms with estimated densities. Partly a demonstration of the use of layout. Also includes lowess smooth or linear model slope, as well as correlation. Adapted from addicted to R example 78 with further modifications suggested by Jared Smith.

`x` |
The X vector, or the first column of a data.frame or matrix. |

`y` |
The Y vector, of if X is a data.frame or matrix, the second column of X |

`smooth` |
if TRUE, then add a loess smooth to the plot |

`ab` |
if TRUE, then show the best fitting linear fit |

`correl` |
TRUE: Show the correlation |

`density` |
TRUE: Show the estimated densities |

`ellipse` |
TRUE: draw 1 and 2 sigma ellipses and smooth |

`digits` |
How many digits to use if showing the correlation |

`method` |
Which method to use for correlation ("pearson","spearman","kendall") defaults to "pearson" |

`smoother` |
if TRUE, use smoothScatter instead of plot. Nice for large N. |

`nrpoints` |
If using smoothScatter, show nrpoints as dots. Defaults to 0 |

`grid` |
If TRUE, show a grid for the scatter plot. |

`cex.cor` |
Adjustment for the size of the correlation |

`xlab` |
Label for the x axis |

`ylab` |
Label for the y axis |

`xlim` |
Allow specification for limits of x axis, although this seems to just work for the scatter plots. |

`ylim` |
Allow specification for limits of y axis |

`x.breaks` |
Number of breaks to suggest to the x axis histogram. |

`y.breaks` |
Number of breaks to suggest to the y axis histogram. |

`x.space` |
space between bars |

`y.space` |
Space between y bars |

`freq` |
Show frequency counts, otherwise show density counts |

`x.axes` |
Show the x axis for the x histogram |

`y.axes` |
Show the y axis for the y histogram |

`xlab.hist` |
Not currently available |

`ylab.hist` |
Label for y axis histogram. Not currently available. |

`title` |
An optional title |

`...` |
Other parameters for graphics |

Just a straightforward application of layout and barplot, with some tricks taken from `pairs.panels`

. The various options allow for correlation ellipses (1 and 2 sigma from the mean), lowess smooths, linear fits, density curves on the histograms, and the value of the correlation. ellipse = TRUE implies smooth = TRUE. The grid option provides a background grid to the scatterplot. )

Adapted from Addicted to R example 78. Modified following some nice suggestions from Jared Smith.

`pairs.panels`

for multiple plots, `multi.hist`

for multiple histograms.
