Bubble plot based on function vaguely based on `bubble`

by Edzer
Pebesma in gstat package. By default, positive values have closed bubbles
and negative values have open bubbles.

1 2 3 4 5 | ```
bubble3(x, y, z, col = 1, cexZ1 = 5, maxsize = NULL, do.sqrt = TRUE,
bg.open = gray(0.95, 0.3), legend = TRUE, legendloc = "top",
legend.z = "default", legend.yadj = 1.1, main = "", cex.main = 1,
xlab = "", ylab = "", minnbubble = 3, xlim = NULL, ylim = NULL,
axis1 = TRUE, xlimextra = 1, add = FALSE, las = 1, allopen = TRUE)
``` |

`x` |
Vector of x-values. |

`y` |
Vector of y-values. |

`z` |
Vector of bubble sizes, where positive sizes will be plotted as
closed bubbles and negative as open unless |

`col` |
Color for bubbles. |

`cexZ1` |
Character expansion (cex) value for a proportion of 1.0. |

`maxsize` |
Size of largest bubble. Prefered option is now an expansion
factor for a bubble with z=1 (see |

`do.sqrt` |
Should size be based on the area? (Diameter proportional to sqrt(z)). Default=TRUE. |

`bg.open` |
background color for open bubbles (border will equal 'col') |

`legend` |
Add a legend to the plot? |

`legendloc` |
Location for legend (default='top') |

`legend.z` |
If a legend is added, what z values will be shown. Default is c(-3,-2,-1,.1,1,2,3) for Pearson-like quantities and a smaller range for proportions that are all less than 1. |

`legend.yadj` |
If a legend is added, how much should the y-axis be expanded to make space for it. |

`main` |
Title of plot. Default="". |

`cex.main` |
Charecter expansion for title. Default=1. |

`xlab` |
X-axis label. |

`ylab` |
Y-axis label. |

`minnbubble` |
Minimum number of unique x values below which extra space is added to horizontal axis (to make plot look better). Default = 8. |

`xlim` |
Optional limits on x-range. |

`ylim` |
Optional limits on y-range. |

`axis1` |
Show the horizontal axis on plot? Option allows turning off for use in multi-figure plots. |

`xlimextra` |
Extra space (see minnbubble above). Default = 1. |

`add` |
Add bubbles to existing plot? Default=FALSE. |

`las` |
Style of axis labels (see ?par for more info). |

`allopen` |
Should all bubbles be open (instead of just negative values)? |
