hboxplot {hexbin} | R Documentation |

If `bin1`

is a `hexbin`

object with an `erode`

component. Then, `hboxplot()`

plots the high counts cells
selected by the `erode`

function. By default, the high counts
cells contain 50 percent of the counts so analagous to the
interquartile range. The function distinguishes the last cells eroded
using color. These cells correspond to one definition of the
bivariate median.

hboxplot(bin1, xbnds = bin1$xbnds, ybnds = bin1$ybnds, density = c(-1,-1), border = c(FALSE, FALSE), pen = c(2, 3), unzoom = 1.04, reshape = FALSE, xlab = "", ylab = "", ...)

`bin1` |
an object of class `hexbin` . |

`xbnds` |
global x-axis plotting limits for multiple plots. |

`ybnds` |
global y-axis plotting limits for multiple plots. |

`density, border` |
arguments for `polygon()` each of
length two, the first for the median, the second for the other cells. |

`pen` |
colors (“pen numbers”) for `polygon()` . |

`unzoom` |
plot limit expansion factor when `xbnds` is missing. |

`reshape` |
logical value to reshape the plot although `xbnds`
and `ybnds` are present. |

`xlab, ylab` |
x- and y- axis labels passed to `plot()` . |

`...` |
additional arguments passed to `plot()` . |

The `density`

, `border`

, and `pen`

arguments correspond
to the `polygon`

function calls for plotting two types of
cells. The cell types, pen numbers and suggested colors are

TYPE | PEN | COLOR |

cells of bin1 | 2 | light gray |

last eroded cells of bin1 (median cells) | 1 | black |

The erode components of the hexbin objects must be present for the medians cells to plot.

When `xbnds`

is missing or `reshape`

is true, the plot
changes graphics parameters and resets them. When `xbnds`

is
missing the function also zooms in based on the available data to
provide increased resolution.

The zoom used the hexagon cell centers. The unzoom argument backs off a bit so the whole hexagon will fit in the plot.

`Hboxplot()`

is used as a stand alone function, for producing separate
legends for `hmatplot()`

and for panels in
`hmatplot()`

.
